Aeolus set for Instrument Telescope Refocussing exercise

Aeolus’s telescope requires periodic collimation and refocussing. To this end, the Instrument Telescope Refocussing activity aims to improve the radiometric performance of the Atmospheric Laser Doppler Instrument (ALADIN)’s telescope by optimizing the throughput at the field stop, the smallest aperture where the return light has to pass. This is done through a change of the temperature settings on the telescope.
