Fix incorrect AVM #20

Closed astrofrog closed 10 years ago

astrofrog commented 11 years ago

Some images have a positive CDELT1 which is incorrect - images of the sky will always have CDELT be negative. I need to add an option (enabled by default) to fix this kind of issue.

The standard explicitly says that the sign in the file doesn't matter, at the end of the day CDELT1 should be interpreted as negative, and CDELT2 positive. Fixed in f056b5ecb7f4a403256a97be5a0ee55aa3dfbb9f
