Changeset 16672 for trunk/psLib/src/fits/psFitsImage.c

Timestamp:

Feb 26, 2008, 2:35:41 PM (18 years ago)

Author:

Paul Price

Message:

Trying to make the scaling of floating-point images a bit more robust. We don't want a write dying because it can't determine a suitable BSCALE and BZERO --- we need to save the write somehow, anyhow! So, if in doubt, use 1 and 0.
