GMOS-S Bias image |
An example bias image for GMOS-S with the E2V CCDs is shown below. In slow read out and using the best amplifiers the bias levels during the commissioning observations were 599 ADU/pixel, 579 ADU/pixel and 627 ADU/pixel for detector 1, 2 and 3, respectively. The greyscale used blow is chosen to show the spatial structure in the bias frame, rather than the relative levels in the three detectors. The data are from the commissioning and have been released as part of dataset GS-CAL20030524.
