X-ray intensity profiles of the CGM-MASS galaxies. Different colors represent data from different galaxies as denoted in (a). The galactocentric radius has been scaled in physical unit (kpc) in (a) and (c), while in r200 in (b) and (d). For panels (a) and (b), the intensity is measured in 0.5–1.25 keV for the hot gas component only, after subtracting various stellar and background components. The solid lines are the best-fit models of each galaxies, with linked slope (β index) but different normalizations. For panels (c) and (d), the intensity is measured in 2–4 keV. Stellar and sky+soft proton background components are not subtracted, but quiescent instrumental background is subtracted and standard exposure correction is adopted.
