Abstract

Some systematic effects in the Planck temperature angular power spectrum compared to differences between several scenario of inflation.

Planck aims at providing the “definitive” temperature angular power spectrum of the relic radiation as errors should be dominated by the cosmic variance up to the fifth peak. It implies a strict control of all possible systematic error sources. Among systematic effects are time dependent ones: cosmic ray hits have a huge short time impact while thermal variability of the HFI instrument and the Planck telescope have a soft but long time influence. I will compare the amplitude of such systematic effects to the precision that must be achieved to separate, for example, different scenario of the inflation.
