In addition to the regular DARKs, there are also open-shutter DARKs (CATG = CALIB, TYPE = PARASITIC, TECH = IMAGE). They include, in addition to the CCD dark current, contribution from the camera enclosure. It most likely originates from Cerenkov radiation due to radioactive decay. These DARKs are regularly taken to monitor all kinds of parasitic light in the dome.

mean_dark normalized to 3600 secs exposure time (QC1 database table uves_dark, column current_dark)

Description: The mean value reported by the MIDAS command stat/image computed on the entire chip is divided by the exposure time in sec and then multiplied by 3600 sec.
