Notes. (a)Determined by fitting Jupiter observations directly in the timelines.(b)Calculated from the main-beam solid angle of the effective beam. These values are used in the source extraction pipeline (Planck Collaboration XXVI 2016).(c)Typical values derived from fitting noise spectra (see Sect. 5). (d)Difference between first and last iteration of the iterative calibration (for 30 and 44 GHz) or E2E 2015 result (for 70 GHz). In 2015, the calibration uncertainty was 0.35% and 0.26% at 30 and 44 GHz, respectively.
