I'm trying to read the cards from a fits file made by indi. CCfits only reads 39 cards. There are 52 in the header. One of the cards it won't read is "BZERO". The reason I ask if it is wonky is that I expected 36 cards in the primary header and the rest in an extension. I may very well be reading the docs wrong, but CCfits is having trouble reading it. I've looked at Fits files from other sources, but haven't found any that exceed the 36 cards yet.

Thanks,
Dave
