All the temperatures are in Celsius. The read noise is the standard deviation of the master bias image (9 combined images). The dark current is the mean of the bias-subtracted, median-combined darks times the gain (1.3) divided by the integration time (300 seconds). The dark current is in electrons per pixel per second, and the read noise is in ADU r.m.s. All of these measurements are below the values given in the camera test report.

Bias Image The mean value of the bias image is 1196. The brightest column at x=2707 has a value of about 1203. Apogeebias.jpg
