Notes. An emission line (Cu) with energy and width fixed at 8.04 keV and 0.01 keV was added to FDCUT and NPEX models. All models include also an absorption like feature at keV
for PCA to account for similar residuals seen in Crab spectra (with the
line energy and width fixed to those obtained from Crab fits). For CompTT model the
may be improved by allowing the line parameters to vary (last column).
(a) Parameter frozen during the fit; (b) [keV]; (c) [10-2 ph keV-1 cm-2 s-1]; (d) [10-3 ph cm-2 s-1]; (e) [atoms cm-2].
