RGS flux to count rate conversion

Figs. 63-65 provide RGS flux to count rate conversion factors for a variety of standard spectral models. Families of curves for various values of the foreground absorbing column density, NH, are plotted. Fluxes and count rates are calculated for the 0.3-2.0 keV band; fluxes are unabsorbed values. All calculations are performed for the -1. grating order.
