a Determined by fitting Jupiter observations directly in the timelines.
c Typical values derived from fitting noise spectra
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 uncertainity was 0.35% and 0.26% at 30 and 44, respectively.
