Abstract

The ESA CMB Planck mission will require an accurate control and removal of instrumental systematics below a level of few mu K. Telemetry information monitoring the instrument status may improve the effectiveness of procedures for the removal of systematic effects in the time domain. A good example is given by thermal instabilities of the 20 K stage of the PLANCK cooling chain. A successful, yet simple approach, based on the use of telemetry information has been developed and is presented here.
