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

Table 1. Summary of the LFI(Planck) Low Frequency Instrument performance parameters

[math]^{ \rm a \, }[/math] FWHMFull-Width-at-Half-Maximum and ellipticity from scanning beam evaluated fitting Jupiter directly in the timelines. [math]\hspace{480mm} [/math] [math]^{ \rm b \, }[/math] FWHMFull-Width-at-Half-Maximum from effective beam estimated from the main beam solid angle of the effective beam. Those are the values used in the source extraction pipeline Planck-2013-XXVIII[2]. [math]\hspace{70mm} [/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.
