For software to appear in the list on the BAA Photometry Database page, there needs to be a way for members to upload observation data files. Have you been able to do this with ASTAP or are you manually entering the observation data?
An explanation on how to convert the AAVSO file format into a format uploadable into the BAA database is given at this link.
Feel free to contact me offline or reply here if you would like any pointers on how to do this. I tested the modified AAVSO file format a while ago, but I am not sure if anyone is actually use this yet.
