Notes. Entry in each column is as follows: 1: central frequency; 2: receiver bandwidth; 3: system temperature; 4: FWHM; 5: number of available feeds; 6: available polarisation channels; 7: telescope aperture efficiency at the corresponding frequency; 8, 9, and 10: parameters A0, A1, and A2 defining the gain curve, respectively; 11: epoch of the gain curve observation; and 12: ELV where the gain is maximised.

We used 43 GHz occasionally with set-ups centred at frequencies slightly different than 43 GHz within a range of a couple hundred megahertz however. For simplicity we always assume 43 GHz as the central frequency.
