Notes. The table lists: (first column) the Baseline calibration (second and third), the calibration methods using other opacity corrections, taumeter and skydip, respectively, and (fourth and fifth) the calibration methods using a photometric correction, PC-demo and PC-point, respectively (see Appendix C). The calibration biases, as defined in Sect. 9.1.1, are reported in the sub-panel labelled “Bias”. The sub-panel labelled “rms” gathers (first row) the total number of observation scans of bright sources (see Sect. 9.1.2) acquired during the Reference campaigns, (second row) the number of selected scans, and (third to sixth rows) the rms calibration uncertainties (Sect. 9.1.2) for Array 1, Array 3, the combination of A1 and A3, and Array 2, respectively.
