Notes. ( † )The values are calculated from the averaged system temperature, characteristic gain curve and the effective aperture size. ( ‡ )In the data, this is labeled as R1 and R2 for each of the two Earth-based sub-arrays. ( † †)These are estimated from RCP-only (see Sect. 2.2), while the others are averaged across dual polarization. ( ‡ ‡)No system temperature measurements.
