Reply To: Issues using BAA Photometry Spreadsheet to calculate based on AIJ data file

Hi John,
I do have some NaN under various fields. I didn’t use AIJ DP for data reduction (I actually used ASTAP to get calibrated science frames) so not sure if the DP Coordinate Converter module was used. I don’t see ALT_OBJ in the Fits header but I have since checked the aperture settings keywords and used the default ones suggested in AIJ doc (JD_SOBS,JD_UTC,HJD_UTC,BJD_TDB,ALT_OBJ,AIRMASS,CCD-TEMP,EXPTIME,RAOBJ2K,DECOBJ2K) – again resulting in some NaN presumably since some don’t exist in the FIits header. I will try to use the CCD DP module to edit/enable those keywords – didn’t realise I would need to do this!
I’ll email you separately to connect and maybe follow up if that’s ok
Thanks, Les
