Notes. λref and νref are the reference wavelength and frequencies of the photometric channels. θ is the beam FWHM. σII and σabs are the data variance and the absolute calibration uncertainty respectively.
Assumed to be for the averageIRAS coverage. σII computed by rescaling this value to actual coverage.
1σ average value in one beam scaled from Planck HFI Core Team (2011b). We actually use internal variance maps for σII.
1σ average value. We actually use a map of the uncertainties (see Sect.2.2.1).
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.
