This page allows the observer to access data and download frames which are useful for the preparation, acquisition and analysis of observations.
Data is kept for set-ups that have been previously requested by observers.
However, the low gain mode has not been tuned and is currently not supported. The chip is operated in MPP mode to reduce the dark current to reasonable levels. Unless otherwise stated, CCD 37 was operated in low read-noise mode for all data acquisition. You can find the most recent measured values of these parameters here. The last three bias frames obtained from the CCD can be found in this table.
