Figure 5. Modelling of the C-K edge region
using the data from XTE J1118+48 after shifting the OBF C-K edge
and increasing the opacity by 13%. The residuals are fitted to a
simple T0 * exp(-[E/E0]^[-a] ) model in the upper panel, where T0
= 0.26, a = 9, and E0 = 0.28670 keV. In the lower panel the residuals
from this fit are shown, heavily smoothed.
