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 [[File:Tab_perf.jpg|thumb|center|655px| [math]^{ \rm a \, }[/math] FWHM and ellipticity from scanning beam evaluated fitting Jupiter directly in the timelines. [math]\hspace{50mm} [/math] [math]^{ \rm b \, }[/math] FWHM from effective beam estimated from the main beam solid angle of the effective beam, see Sec. 6.2. Those are the values used in the source extraction pipeline #planck2013-p05 Planck-2013-XXVIII . [math]\hspace{42mm} [/math] [math]^{ \rm c \, }[/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.
