Notes. All errors are in the 90% confidence range. (a) The line widths E1 and E2 were frozen to the value of 1 ev in the phase-resolved analysis because they are too narrow to be resolved by the pn detector. Nevertheless, E2 in the phase-averaged spectra is broader and has a width value of eV. (*) Parameter frozen.
