AIJ: FITS Header Settings

I'm totally confused about this dialog, what it does, and what information it needs to get from the existing FITS header. I've been using a video from Patriot Astrophotography as a guide to the data analysis procedure, and the narrator in that video says that all 6 of the keywords in the top group of fields in the dialog have to be found somewhere in the existing FITS header. Well, in my science images, basically none of them are, except for the observatory name keyword which I assume was put there by ASTAP when it converted the Canon RAW images to FITS. But there is no keyword for the object of interest, no keywords for the target RA and DEC, nor for the site lat/long coordinates. Are my FITS images unusable by AIJ, is there another step I need to perform to get that information in the header, or am I being misled by the video?
