I need to change a few values in a couple of FITs image headers to fit with some test data I have. Therefore I'm trying to hack a FITs image header at the minute to run with the application.
However at the minute - I can't even see the header, never mind hack it. I run Ubuntu.
Can anyone advise some software to view the FITs - perhaps even hack it?
edhead seems to do the job very well. Only piece of software I have found that allows you to edit the header at the command line.
