Revision as of 16:19, 17 March 2013
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
FWHM and ellipticity from scanning beam evaluated fitting Jupiter directly in the timelines. 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 #planck2013-p05 Planck-2013-XXVIII . 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.
