| 27/06/2023 | Amended output file of observations. The csv files contained some commas in the instrument field, replaced with spaces. The details of the CCD measurements included carriage returns as these were new lines in the web based table. These are now a colon with a space to prevent new lines. The visual estimate recalculation reason could also include new lines, for similar reasons. These have been replaced by semi-colons with spaces. |
| 17/06/2023 | Modified the duplicate observation check in the upload so that it also check location and instrument. These are a little different to the other fields in the check as they are nullable fields. |
| 11/03/2023 | Created new upload file layout CCD/CMOS V2.03. Based on previous layouts but with more meaningful names for the import fields. Updated the layout guide and sample files. |
| 11/06/2022 | Extended valid sequence version from 1-999 to 0-999. Zero will be used for the new sequence just for recalculation. |
| 02/04/2022 | Fixed deprecated trim of a null value in the upload process. |
| 06/02/2022 | Minor changes for PHP and MySQL compatibility on new server. |
| 26/10/2021 | Fix to the individual observation add and edit screens to allow CMOS. CCD is always entered as the default method but no easy way to change this behaviour at this time. |
| 11/09/2021 | Tweaks to get ready for migration to PHP 7 and MySQL 8. Changes for deprecation of implode function. |
| 07/08/2021 | Amended the stats to add a digital option that amalgamates CCD, CMOS and DSLR. |
| 30/05/2021 | Updated the tolerance for magnitude check on transformed CCD observations from 0.3 to 0.4 magnitudes. |
| 07/05/2021 | Added to support to upload and display CMOS observations. |
| 17/04/2021 | Updated CCD-Layout-Minimum upload file format to contain additional important data. |
| 31/01/2021 | Added examples of bulk upload file format. |
| 11/01/2021 | Correction to upload layout CCD/DSLR BULK V1.00. It was not reading the magnitude fainter than magnitude qualifier when it was used. |
| 09/01/2021 | Correction to upload layout AAVSO EXT BAA V1.00. It was not reading the magnitude fainter than magnitude qualifier when it was used. |
| 29/10/2020 | Made the file upload type case insensitive. |
| 06/06/2020 | Fixed bug with login screen when wrong username or password was entered. |
| 05/06/2020 | Updated to be compliant with PHP 7. |
| 02/06/2020 | Increased maximum file upload from 18 to 35. |
| 29/12/2019 | Created new role for editing objects and updated screens to recognise role. |
| 22/12/2019 | Altered edit object alias name list to a maximum of 10 rows. Previous setting was 100 rows and this was becoming very slow due to the number of object ids in the list on each row. |
| 26/10/2019 | Added version 2.07 of the BAA Photometry Spreadsheet. Bug found by Tony Vale, the AAVSO export sheet was not updating the method from CCD to DSLR. |
| 10/02/2019 | Enhancement to cope with a variable number of comparison stars per row in uploaded data file. Will ignore sets of columns where the comparison designation is omitted. This includes a tweak to upload format CCD/DSLR V2.02 so that comparison star alias and type are no longer mandatory. |
| 13/01/2019 | Bug fix for recalculation of Dave McAdam era sequences with hybrid sequences like '3,1' and estimates like '{D}+2' with curley braces to indicate comparison star label from the first sequence of the two. |
| 08/01/2019 | Copied over all notes on submitting observations from the VSS web pages into the pages on the main database website. |
| 06/01/2019 | Introduced recalculation of Visual observations to the latest sequence when reviewing data for an object.
While the code exists in the website for recalculating CCD and DSLR observations, it has not been enabled since original data may include chart magnitude error values not in the database, it is only possible for V filter observations, and many charts are not present for digital observations. |
| 06/01/2019 | Support for Exoplanet and Asteroid photometry as well as Variable Stars. Observers now have to select object type when they create a new object. Various web pages updated to include object type. |
| 06/01/2019 | Rebranding as BAA Photometry Database. This includes updating the style to more closely match the BAA Photometry Database. |
| 23/12/2018 | Added support for fainter than and brighter than digital observations in new upload format 'CCD/DSLR V2.02'. Fainter than observations are identified by a [ or < at the start of the VarAbsMag field, and brighter than observations by a ] or > at the start if the VarAbsMag field. |
| 19/08/2018 | Replaced sequence data SQL as orphaned comparison star alias names and magnitudes were being left in the database when one but not both of magnitude or alias were deleted. |
| 04/08/2018 | Added check for existing AUID (AAVSO Unique Identifier) when adding new objects and updating existing objects. |
| 10/12/2017 | Set 8,153 duplicated observations to deleted status. Matching criteria used to identify duplicates:
Julian Date (exact) Variable Designation Observer Magnitude Filter |
| 23/04/2017 | Added new page on star name conventions with a link on the upload screen and homepage. |
| 22/02/2017 | Fixed issue with + being interpreted as a space character in object ids when selecting the object summary in the variable star list. Fixed by replace + characters with %2b in the hyperlink. |
| 01/01/2017 | Amended observation download to use pipe character | rather than new line between the different CCD measurements in a single observation. Also fixed a bug with downloading data with Firefox where the filename would be truncated at the first space. Due to Firefox only recognising a filename string enclosed by double quotes. |
| 17/09/2016 | Implemented new data download functionality. Observation download button now moved to main data screen. Additional fields added to table and download. |
| 14/09/2015 | Removed data download functionality due to issue. |
| 29/08/2015 | Amended the sequence data screen from showing the full 4 decimal places in the database table, to showing a truncated 3 decimal places. Changed sequence table column width by removing table setting to be across the whole screen. |
| 12/08/2015 | In the single and bulk observation edit screens, replaced the variable star list used when selecting observations with the main object_id rather than the object_alias. Left the variable that is entered/updated as the object_alias since this must match the observation table. |
| 09/08/2015 | Behind the scenes changes released to enhance the magnitude recalculation prototype pages. |
| 01/08/2015 | Behind the scenes changes released to enable the prototyping of the magnitude recalculation pages. |
| 28/06/2015 | Added link to the database statistics page for logged in users. The link can be found on the homepage under the General heading. |
| 28/12/2014 | Optimisation of the upload process to get it to run more quickly and hopefully avoid 60 second timeouts on the web. Modified the procedure that first uploads the data to the temporary tables so that the estimates and measurements tables are only hit the once. Modified the commit process to run 1 rather than many delete commands on each of the temporary tables. |
| 10/12/2014 | Altered order of displayed and exported data table from ascending Julian date to descending Julian date. |
| 20/10/2014 | Further modification to the JavaScript that is used to convert UT to JD in the Review Data page. The conversion had stopped working in Google Chrome giving NaN rather than a number. |
| 19/10/2014 | Modification to the JavaScript that is used to convert UT to JD in the Review Data page. The conversion had stopped working in Google Chrome giving NaN rather than a number. |
| 17/10/2014 | Correction to observer summary by star. Sometimes zero magnitude was being returned for the first or latest magnitude when it should not have been. |
| 03/08/2014 | Added optional start and end Julian Date to the database summary page. |
| 14/06/2014 | Added instrument and camera under the heading of equipment to the data table page from review data for a star. |
| 26/05/2014 | Modified 986 observations and 354 star alias names to remove multiple spaces from names. These were interfering with the operation of some web pages. |
| 26/05/2014 | Modified data entry cleaning to strip out all multiple spaces and replace with single space. Multiple spaces had been causing problems between the database and web pages, since HTML strips out multiple consecutive space characters to display only single spaces on the screen. |
| 22/05/2014 | Added filter to the summary of uploaded observations page. |
| 13/05/2014 | Update to new column "Estimates / Comparison Stars" to improve formatting. The separator between multiple estimates and comparison stars is now a semi-colon and the text is preceded by a space so that Excel will not try to interpret estimates as formula or dates. |
| 09/05/2014 | Added new columns "Estimates / Comparison Stars" and "Chart / Sequence" to the data table produced by the light curve generator. |
| 06/05/2014 | Corrected mistake in the Year and Month summaries by Observer, Star and the whole database. The Julian Date was not being correctly converted to UT, but was often giving a date a day in the future of the true date. |
| 04/05/2014 | Added options of 'Instrumental-Transformed' and 'PreCalculated-Transformed' for entry of CCD data. 'Instrumental-Transformed' has a different error tolerance on the magnitude check as the check cannot transform the data. |
| 30/04/2014 | Added check on visual file upload to make sure hour does not contain a decimal. |
| 23/04/2014 | Modified visual upload so that the estimate is not mandatory. |
| 18/04/2014 | Tweaked the visual upload magnitude tolerance from <=0.05 to <=0.099 magnitudes to cope with magnitudes uploaded to 2 decimal places. |
| 17/04/2014 | Tweaked the visual upload magnitude tolerance from <0.05 to <=0.05 magnitudes to cope with magnitudes uploaded to 2 decimal places. |
| 15/04/2014 | Released star summary web page including count of observations by year and month and count of observations by observer. This can be accessed by clicking the Object Id hyperlinks in the Variable Stars standing data page. |
| 14/04/2014 | Released enhanced observer summary including count of observations by year and month. |
| 10/04/2014 | Further update to filter colours in the light curve generator to make them more distinct. |
| 09/04/2014 | Updated and standardised filter colours in the light curve generator to make them more distinct from one another, except when they are for similar filters. |
| 05/04/2014 | Fixed bug with web pages for editing variable star names and alias names. They were not allowing the star names or alias names to be updated with new names. |
| 22/03/2014 | Changed default dates in the Light Curves to UT rather than JD. |
| 22/03/2014 | Enhancements to the date check in the upload program so it will work for pre-1900 dates. |
| 11/03/2014 | Database updated with all Visual and CCD observations received to date. |
| 09/03/2014 | Fixed bug with 'Manual Enter Observations' screen. Observations were being added but the observation variable was being accidentally passed between procedures due to variable scope. This showed as an erroneous additional measurement for Visual observations. |
| 06/03/2014 | Enhanced UT calculation to check for valid hour and minute values. |
| 02/03/2014 | Added options to filter bulk observation edit by Sequence and Location, including "BLANK" sequence and location. Also fixed a bug introduced by this change to the individual observation edit screen, and moved the fetch and reset buttons to the left hand side. |
| 28/02/2014 | Enhancement to UT display on light curve so that hh:mm is only shown for periods of 5 days or less. Note this does not work when zooming as the date format is fixed when the light curve is created. Also made minor fix to selection page as the Reset had stopped working with the change on the 27th Feb. This should now work again. |
| 27/02/2014 | New buttons on light curve and data table to modify selection parameters. |
| 23/02/2014 | Added link to BAAVSS homepage in top left corner when on the BAAVSS Database homepage. Also made the link to the BAAVSS homepage more prominent in the General section by moving it to the top of the section. |
| 23/02/2014 | Modified default of 5 estimates per visual observation in Manual Observation Entry screen to a default of 1 estimate per observation. |
| 22/02/2014 | Release of version 2 of the website, to enable observers to upload and edit their own observations. |
| 25/10/2013 | Preliminary version 2 website complete. This includes ability for users to load their own data. |
| 24/08/2013 | Uploaded 2011 and 2012 observations from the visual database. This includes a lot of historic observations as well as those received during 2011 and 2012. In total 117,070 new observations. |
| 10/08/2013 | Uploaded CCD observations received by 10th August 2013. |
| 14/04/2013 | Uploaded CCD observations received by 31st March 2013. |
| 24/02/2013 | Fixed minor bug with filtering on a star. After applying the filter any text after a space in the filter by box was being removed. Now all text is retained. |
| 27/10/2012 | Uploaded CCD observations received by 27th October 2012. |
| 19/08/2012 | Corrections to 2,621 Julian Dates pre 1900. |
| 29/04/2012 | Minor changes to light curve page. Moved reset zoom above chart title so this can be cut out of screen prints. Added link to new page of fixes to known light curve issues. |
| 14/04/2012 | Minor change to End Date Julian Date calculation in Review Data sheet.
Adds 1 day to quoted UT so the JD is the end of that day. E.g. enter 31st May as UT and JD will be calculated as start of 1st June. |
| 09/04/2012 | Corrected 304 CCD observations with reported magnitude problems. |
| 09/04/2012 | Uploaded CCD observations received by 6th April 2012. |
| 20/03/2012 | Light curve legend moved to bottom left hand corner. It is the intention that users will be able to relocate the legend themselves in a future release. |
| 11/03/2012 | Set 14,213 duplicated observations to deleted status. Matching criteria used to identify duplicates:
Julian Date (not just matches but must be recorded to at least 4 decimal places to avoid accidental removal of observations made at similar time but full time not recorded) Variable Designation Observer Magnitude Filter Only 2 or 3 duplicates (there are a small number with many duplicates. These will be checked separately.) |
| 19/02/2012 | Major update to variable designations and alias designations. |
| 31/12/2011 | Created page for list of recent updates. |
| 31/12/2011 | Added summary page of observer's observations. Accessed by pressing Observer Id hyperlinks in observer list. |
| 31/12/2011 | Added download buttons to list tables. |
| 31/12/2011 | Split observer names into surname and initials. |
| 30/12/2011 | Created filter button on data page to allow users to search and filter the list of variable stars. Note this also searches the full list of alias names held within the database. |
| 29/12/2011 | Loaded all CCD data received to date. |
