Notes.

^(a1)

Channel map reference frequency and channel identifier.

^(a2)

Number of bolometers whose data were used in producing the channel map.

^(b1)

Mean value over bolometers at the same frequency. See Sect. 4.2 in Paper A.

^(b2)

As given by simulations.

^(b3)

Variation (rms) of the solid angle across the sky.

^(b4)

FWHM of the Gaussian whose solid angle is equivalent to that of the effective beams.

^(b5)

Mean FWHM of the elliptical Gaussian fit.

^(b6)

Ratio of the major to minor axis of the best-fit Gaussian averaged over the full sky.

^(b7)

Variability (rms) on the sky.

^(c1)

Estimate of the noise per beam solid angle as given in (b1).

^(c2)

Estimate of the noise in intensity scaled to 1° assuming that the noise is white.

^(c3)

Estimate of the noise in polarization scaled to 1° assuming that the noise is white.

^(d)

Calibration accuracy (at 545 and 857 GHz: the 5% accounts for the model uncertainty).

^(e1)

According to the Béthermin et al. (2012) model, whose uncertainty is estimated to be at the 20% level (also for constant νI_ν).

^(e2)

Zero-level correction to be added on Zodical-light-corrected maps.

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.
