Actually, I believe it's misnamed.  This has been discussed with Ed Hamrick
and should be in the archives.  It does not change the actual gain between
the CCD and the A/D, but the exposure time.  To quote from Ed Hamrick (who
wrote ViewScan) from the rec.photo.digital newsgroup:

"The "Analog gain" in the Nikon is a bit misleading.  It's actually
just the exposure time for each of red, green, blue, and infrared."
