Illustration of the method used to produce LFI synthetised beams weighted for the radiometer response (in this case LFI 18M). The vertical lines identify the frequencies at which the beam has been simulated within the radiometer bandpass T(ν). The results are then used to construct a weigthed 4π beam for each radiometer. Details on the bandpass measurements can be found in Villa et al. (2010).
