Fits Header and Image Integration Problems

[Lex]

Hi guys,

First "Problem":

When I open Images recorded with AA5, PI gives me error messages that the Fits Header ( Metadata ) is not correct or something like that? Is there a way to avoid that? I have a set of nearly 4 hours and I really do not wanna dump this...

Second "Problem":

After aligning a set of images, even having told the program to save files to a certain folder, it sometimes occures that PI doesn't save and you'll have to manually save file by file... Is this issue known.
Also why isn't it possible to integrate the resulting not saved images after the alignment procedure?

I am using RC3 on Mountain Lion 8 Gb MBPro.

Best

Hi,
As any standard, the FITS standard is open to interpretation and erroneous implementations (by other programs...). There quite a few posts on the issue of FITS file reading in the PI forums.
To make things short, the problem is usually due to either an erroneous FITS header (for example BZERO is wrong), a file with data that does not match the header or the use of floating point data.  Some of it can be rescued by setting some options in the FITS file format.

I have hacked a small script (attached) that dump the header of a FITS file to a text file (of the same name, in the same directory, with extension txt). It does not use the PI image load, but directly read the files. You should be able to read the header of one of your problematic files and post it here.  Surely somebody can then help you.
