Thanks Larry. I recently purchased a new monitor because the old
monitor turned anything gray to a sickly purple color so processing
images was difficult. I just looked at the image again and see that the
background looks too bright but the red is what is in the data. I would
like the center whitish portion to be slightly more aqua color but I'll
have to reprocess the whole thing.

Thanks again - Cal
