FIT files

[BramMeijer]

Hello,
I was trying to open some FIT files in the batch pp script, but all my fit files won't open anymore...
They could be opened a while ago, any suggestions?
Cheers

Hi,

Please use the FITS File Verifier service by NASA/HEASARC to check if this is a valid FITS file.

I will try that option.
But i never had issues opening those same fit files before.
ty, Bram

Hi Bram,

Then I need the original FITS file that is causing problems. Can you upload it?
