COMMENT   THE KPNO "VIDEO CAMERA" IS AN INTEGRATING DIGITAL TELEVISION SYSTEM
COMMENT   WHICH USES AN  RCA ISIT VIDICON TUBE AND ACCUMULATES THE IMAGE IN
COMMENT   A 256-SQUARE 20-BIT RAM DURING THE INTEGRATION.
COMMENT   THIS IMAGE HAS BEEN CORRECTED FOR THE DARK CURRENT AND GAIN VARIATIONS
COMMENT   ACROSS THE FIELD. I.E., THE DARK IMAGE WAS SUBTRACTED, AND THE FLAT
COMMENT   FIELD IMAGE WAS DIVIDED INTO THE RAW IMAGE. BECAUSE THE FLAT WAS NOT
COMMENT   NORMALIZED IN THIS CASE, THE RESULTING RATIO IMAGE IS OF ORDER UNITY.
COMMENT   THIS IS A QUANTUM NOISE LIMITED IMAGE IN RELATIVE INTENSITY UNITS.
