Notes. The continuum was fit separately with the MCAE and the AC models. In both cases a Gaussian absorption line was used to model the possible CRSF. All errors are in the 90% confidence range. Kdisk is the normalization parameter for the diskbb component. Namely, Kdisk = (Rdisk/D10 kpc)2 cosi, where Rdisk is the inner radius of the disk in km, D10 kpc is the distance in units of 10 kpc, and i is the inclination. Khot is the same as Kdisk, but for the hot MCD component. KcPL and KPL are the power-law normalization parameters in units of photons/keV/cm2/s at 1 keV. Kgabs is the line depth. The optical depth at line center is .
