Notes. Columns are as follows: (1) Models: pl = powerlaw, bbdy = black body, zpcf = partial covering absorber, and zxipcf = ionized absorber model. (2) Absorption in units of 1022 cm−2; (3) power-law photon index; (4) kT in units of keV of the black body, or ionization parameter log ξ of the ionized absorber; (5) covering factor; and (6) goodness of fit, reduced χ2. If no errors are reported, the quantity was fixed. For all fits the column density at z = 0 was fixed to the Galactic value of 3.96×1020 cm−2.
(1)bbdy parameters fixed at low-state value.
(2)Fits using Cash statistics (Cash 1979).
