The problem is significant: A fits file has no concept of frames.  But kst wants to know how many frames a data source has so it knows what it can ask for.  It must be that now the data source generates NF from the size of the first data object in the file, so it would be expected that it would also generate INDEX from the first data object in the file.  Anything else, and we have bigger fish to fry (like over or under reading fields).

I suggest that for the short term, we generate INDEX and NF from the first data object in the file.

For the long term, I think we need to some how break a fits file into sub-data sources each with equal sized fields as Piolib apparently does.
