Notes. The spectral model is: TBABS_MW * (ZCUTOFFPL_scatt+ TBABS_int*(PCFABS*ZCUTOFFPL_primary + GSMOOTH*PEXMON)). These have all been calculated from an MCMC chain, in XSPEC, using 8 walkers and 160000 steps. The errors correspond to 90 % confidence. Parameter values prefixed with an = are tied to the given component. The constant is included to account for calibration differences between XRISM-xtend and NuSTAR.
