LFI optical performance.
  ET FWHM e XPD Ssp Msp
70 17 dB at $22^\circ$ 13.03 1.22 -34.73 0.17 0.65
44 30 dB at $22^\circ$ 26.81 1.26 -30.54 0.074 0.18
30 30 dB at $22^\circ$ 33.34 1.38 -32.37 0.24 0.59

Notes. All the values are averaged over all channels at the same frequency. ET is the horn edge taper measured at  $22^\circ$from the horn axis; FWHM is the angular resolution in arcmin; e is the ellipticity; XPD is the cross-polar discrimination in dB; Ssp is the Sub-reflector spillover (%); Msp is the Main-reflector spillover (%). See text for details.
