Fluxes obtained with simple disk plus power law model |
Different values of mass, distance and inclination were chosen:
Mass/Msun: 5, 10, 15
Dist/kpc: 5, 10, 15, 20
incl/deg: 55, 65, 75, 85
=>48 {M, d, i} triplets.
Model: phabs*kerrbb
Frozen parameters:
kerrbb.norm=1,
kerrbb.eta=0 (standard Keplerian disk with zero torque
at the inner boundary),
kerrbb.Mbh=one of the choices from above,
kerrbb.dist=one of the choices from above,
kerrbb.incl=one of the choices from above,
kerrbb.rflag=1 (self-irradiation is included),
kerrbb.lflag=1 (limb-darkening is included).
Global parameters (allowed to vary, but tied between observations):
phabs.nh,
kerrbb.spin.
Local parameters (allowed to vary between observations):
kerrbb.Mdd (mass accretion rate of the disk in units of 10^18
g/sec),
kerrbb.hd (spectral hardening factor).
Number of free parameters in the simultaneous fits = 54
