Notes. Fit to the broad-band XMM-Newton spectra, from 0.3–10 keV, of a power law absorbed by the Galactic column (model TBABS, NH = 1.9 × 1020 cm−2). Errors are at the 90% confidence level. Observations of 2016-09-08, 2016-09-16, 2016-10-30, and 2016-11-27 use the EPIC-pn, MOS1, and MOS2 data; the 2018-04-25 observation only uses the EPIC-pn data.
