The LFI performance are summarized in Table 1 below. All the details can be found in the LFI data processing paper [1]Planck-2013-II .


Table 1. Summary of the LFI performance parameters

[math]^{ \rm a \, }[/math] FWHM and ellipticity from scanning beam evaluated fitting Jupiter directly in the timelines. [math]\hspace{480mm} [/math] [math]^{ \rm b \, }[/math] FWHM from effective beam estimated from the main beam solid angle of the effective beam. Those are the values used in the source extraction pipeline [2]Planck-2013-XXVIII . [math]{\hspace{35mm}}[/math] [math]^{ \rm c \, }[/math] White noise per pixel computed from half-ring difference maps. Those values are within the 1% with the white noise sensitivity computed directly on the timelines, taking in account the actual mission time minus the manoeuvres and bad-science flagged data.
