Hi Dennis,
Haha! You can keep that python! I'll stick with the programming language.
I found this page (
https://data.sdss.org/datamodel/file...perset_v3.html) and it lists the contents of the huge FITS file. In particular it shows the 2 FITS header sections, and then the rest of the data, stored as binary objects.
As I suspected, the FITS file is effectively a huge spreadsheet (there are 97 data columns) with all manner of information, which is why an image processing program won't be able to open it.
Someone with more programming skills than I have could whip something up to pull the data out and massage it into something like a CSV file for viewing in Excel or the like.
Sorry, I can't help much more on this one...
Regards,
V
