Notes. Values for the shot noise are given in the photometric convention νIν = cst.
From Planck Collaboration XXX (2014), shot noise from their Table 9, corrected to νIν = constant and corrected from the calibration difference between PR1 and PR2 data releases (at 545 and 857 GHz). At 217 GHz, the contribution from radio sources has also been removed.
From Mak et al. (2017).
