We currently handle HJD conversion for additive loads for this scenario:
What about additive loads of file-based formats only where one or more of which are HJD based? Either the RA/Dec must be requested via dialog or obtained from one of the files. CSS has RA/Dec info, but it seems to differ per observation (!). ASAS has RA/Dec info also, but it differs per dataset. So, one can't just say: based upon the AID data I loaded, now that I am loading an ASAS/CSS file, I can apply the same RA/Dec to all AID observations for HJD conversion purposes.
How to solve this in a general way?
As part of this, AID additive load should be possible. The current approach should work once this is enabled.
