383L+ FITS Header

[smithn00]

Can the data created in the FITS header be changed?  Can I select what items go into the FITS header?

It will depend a little on what software you're using, but generally speaking you should be able to change some of the header information, but some parts will be locked.

I'm sorry that's a bit of a vague answer, but I hope it helps!
