Notes.

^(a)

The HFI default maps do not include removal of zodiacal emission.

^(b)

Includes the absolute uncertainty (0.25%) of the calibration standard used, which is the CMB dipole estimated by WMAP7 (Hinshaw et al. 2009).

^(c)

A zero level has been removed from the LFI maps (−300.84, −22.83, and −28.09 μK_CMB at 30, 44, and 70 GHz), but not from the HFI maps. The value given in this table corresponds to an estimated zero level of Galactic emission (Planck Collaboration VIII 2014) in the maps, which include zodiacal emission. For total emission studies, the level contributed by the CIB must be added (Planck Collaboration VIII 2014).

^(d)

β is the temperature spectral index of the source (Planck Collaboration IV 2014) and Δα is the difference in source spectral index from −1 (Planck Collaboration IX 2014). For α = − 1, νI_ν = const. following the IRAS convention. No uncertainties are assumed on α and β.

^(e)

For the HFI channels, we show the upper limit in solid angle change due to colour correction from a planet spectrum source (roughly ν²) to IRAS convention (ν^-1).
