2D confidence contours (1, 2, and 3σ) of the bulk velocity and velocity dispersion measurements of our new regions (calibration and GO pointings). The red contours indicate a joint fit between the E and NE regions (see Fig. A.3 for their individual fits). The crosses mark the best-fit parameters and their 1σ uncertainties, including also all PV data (ten sub-regions; see Sect. 3). The pink cross indicates the cold ICM component in the 2T model for region E (see Sect. 2).
