The new sky load requires some changes, respect to the old one, to allocate 3 noise sources. The position and shape of sources comes from HFI and LFI requirements . More details are given in Errore.

IASF-Bo has taken in charge the responsibility to perform cryogenic tests on two representative panels to verify that are compliant with needs. Tests have been performed on procedure given in AD01, mainly based on the same followed in year 2003 to verify compliance of the original sky load.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
