The LFI performance are summarized in Table 1 below. All the details can be found in the LFI data processing paper #planck2013-p02 Planck-2013-II .


Table 1. Summary of the LFI performance parameters

[math]^{ \rm a \, }[/math] White noise per pixel computed from half-ring difference maps. Those values are within the 1% with the withe noise sensitivity computed directly on the timelines, taking in account the actual mission time minus the manoeuvres and bad-science flagged data [math]^{ \rm b \, }[/math] FWHM and ellipticity from scanning beam evaluated fitting Jupiter directly in the timelines. [math]\hspace{50mm} [/math] [math]^{ \rm c \, }[/math] FWHM and ellipticity from effective beam evaluated as mean from different position on the sky. [math]\hspace{42mm} [/math] [math]^{ \rm d \, }[/math] FWHM from effective beam evaluated as FWHM[math]_{eff} = \sqrt{\frac{Ω}{2π}} · 2 · \sqrt{2 \log 2}[/math], where Ω is the mean beam solid angle of the effective beam. Those are the values used in the source extraction pipeline #planck2013-p05 Planck-2013-XXVIII
