Notes.

(a)

Determined by fitting Jupiter observations directly in the timelines.

(b)

Calculated from the main beam solid angle of the effective beam, Ωeff = mean(Ω) (Sect. 6.2). These values are used in the source extraction pipeline (Planck Collaboration XXVIII 2014).

(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.

(d)

Values derived from fitting noise spectra (Sect. 8).

(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 < < 250 (see Planck Collaboration V 2014).

(f)

Peak-to-peak difference between 99% and 1% quantiles in the pixel value distributions from simulated maps (see Planck Collaboration III 2014).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
