Summary of LFI data characteristics
Quantification of the performance of LFI(Planck) Low Frequency Instrument is summarized in Table 1 below. All the details can be found in the LFI(Planck) Low Frequency Instrument data processing paper Planck-2018-l02.

|Scanning beam FWHMFull-Width-at-Half-Maximuma [arcmin]||33.10||27.94||13.08|
|Scanning beam ellipticitya||1.37||1.25||1.27|
|Effective beam FWHMFull-Width-at-Half-Maximumb [arcmin]||32.29||27.00||13.22|
|White noise level in timelinesc [μKCMBCosmic Microwave background s1/2]||147.9||174.0||151.9|
|Overall calibration uncertaintyd [%]||0.17||0.12||0.20|
c Typical values derived from fitting noise spectra
d difference between first and last iteration of the iterative calibration (for 30 and 44 GHz) or E2E 2015 result (for 70 GHz). In 2015 the calibration uncertainity was 0.35% and 0.26% at 30 and 44, respectively.
