Imaging

Like for the optical (see under ALFOSC) specific catalogues were provided that are included in the TCS upon start-up.

All NOTCam detector quality control data are taken with darks and dome-flats while NOTCam is mounted on the telescope during daytime. There have been various problems with variable lamps as well as variable daylight leakage in through hatches etc. that make the exact calibrations like linearity tests and shutter tests difficult. We need stable lamps that can be turned down sufficiently low. Then the telescope will be pointed to the best altitude to avoid daylight leakage while doing the quality control.

A light regulator for the dome light from the control room was installed, but it did not worked well as the light level was very unstable. New electronics was bought, but these need to be tested.
