Table 6: As for Table 5, but for the cryo-stage of the SPOrt radiometers. As a worst case, we assume $A_{\rm p} = 0.1$ dB and $A_{\rm omt} = 0.2$ dB the attenuations of polarizer and OMT, respectively. Anyway, the offset fluctuations are marginally dependent on their values, $S\!P_{\rm pol}$ being the dominant term.
