Best fit to the non-dip, intermediate dip and deep dip spectra showing in each case the data, total model, blackbody and Comptonized emission components and the emission lines at 1 and 6.6 keV. It can be seen that in the best-fit model, the blackbody curve peaking at 3 keV does not change during dipping as it is not subject to absorption.
