Some parameters of the O VIII and O VII bands plotted against the RGS position angle. (a) C-stat./d.o.f. values from the CIE and shifted-CIEs modellings on the 0.60−0.77 keV band (O VIII and Fe XVII). (b) Temperatures derived from the two modellings. (c) EM_S/EM_N profile obtained from the shifted-CIEs method. (d) Same as (a), but on the 0.45−0.62 keV band fitting (N VII and O VII). The results are from the CIE, shifted-CIEs (0.14 keV), and CIE+CX modellings. (e) Temperatures derived from the CIE modelling. (f) Flux contribution of the CX components to the O VII line.
