Thanks for the help, James.

I do think I have scaled and gridded the data correctly.
The secret to getting "bright" images, compared to what
I was getting most of the day, appears to be knowing
the esoteric numbers necessary to do a piecewise-scaling
of the image into byte values, rather than doing a simple
BYTSCL. I have an article in the works that I think will
help people produce better results. Perhaps you will have
more suggestions when you read the article. I would
certainly welcome them. :-)

Cheers,

David
