$^{\rm a}$ Determined by fitting Jupiter observations directly in the timelines.

$^{\rm b}$ Calculated from the main beam solid angle of the effective beam, $\Omega_{\rm eff} = \hbox{mean}(\Omega)$. These values are used in the source extraction pipeline Planck-2015-A35.

$^{\rm c}$ White noise per pixel computed from half-ring difference maps. These values are within 1% of the white noise sensitivity computed directly on the timelines, taking into account the actual integration time represented in the maps.

$^{\rm d}$ Values derived from fitting noise spectra.

$^{\rm e}$ Sum of the error on the estimation of the calibration constant (0.25 %) and the square root of the squared sum of the following errors: beam uncertainty; sidelobe convolution effect; and unknown systematics as measured from the power spectrum at $50 \lt \ell \lt 250$, see Planck-2015-A05.

$^{\rm f}$ Peak-to-peak difference between 99% and 1% quantities in the pixel value distributions from simulated maps, see Planck-2015-A03.
