Variation of the X-ray background model component best-fit parameters over galactic latitude (gal b). (a) Best-fit reduced fit statistic (cstat/d.o.f.). The solid line is the average, while the dashed lines show the 1σ standard deviation. (b) The LHB normalization; (c) The CGM plasma temperature (APEC). (d) The CGM normalization. (e) The hot corona component normalization (kT = 0.7 keV). We also overlaid two Galactic mass profiles, based on Bienayme et al. (1987) and McMillan (2017). The profiles were kindly provided by N. Locatelli, averaged over the projected profiles at l = 175°−230°. The scale of the profiles is arbitrary, chosen for the best visual representation. (f) The extra-galactic component (double-broken power law) normalization. For b–f the triangles facing down indicate gal l < 200° while facing up triangles are used for l > 200°.
