...

  • The spectra are extracted from 3-6 arcmin annulus, centered on the cluster center
  • The scripts use a 1-temperature phabs x mekal model.
  • The column density is from Kalberla et al. (2005) and the absorption cross-sections are from  Balucinska-Church & McCammon (1992).
  • The scripts use the metal abundance table from Grevesse & Sauval (1998).

 

                               INDIVIDUAL FITS

                Each cluster and instrument fitted separately (see Table A.1 in Kettula et al., 2013)

...

  • "X" refers to XIS unit (0,1, or 3)
  • "Y" is the cluster name
  • "Z" refers to the band used in the fit (0520 = 0.5-2.0 keV;  2070 = 2.0-7.0 keV

 

                                    JOINT FITS

For each cluster all XIS instruments are fitted simultaneously, forcing the temperature and metal abundance equal between the instruments, and allowing Oxygen column density of the  contaminant to vary (see Tables 5 and 6 in Kettula et al., 2013)
