Notes. These values were calculated by spectral fitting with the XSPEC software package (Sect. 3.1). Fluxes (Cols. 2−4), normalizations (Cols. 4 and 6), and column densities (Cols. 5 and 7) are in units of erg cm-2 s-1, cm-5, and 1022 cm-2 respectively. Absorbed (upper) and unabsorbed (lower) fluxes are given for each observation in the soft, medium, and hard bands for which light curves were created (Sect. 3.2). Normalizations and column densities have high and low error bars as indicated. In the case of revolution 2272, we split the observation at phase 0.624 and performed spectral fitting of the resulting spectra as well as the whole observation (Sect. 3.1). Observation 2272_1 represents the spectra derived from the data between the start of observation 2272 and phase 0.624, while 2272_2 is from phase 0.624 to the end of the observation. See Sect. 3.1 for abundances used for all fits.
