XMM-Newton-EPIC (2011 Nov.) and Swift-XRT (2013 Aug.) spectra of V751 Cyg, fitted with two absorbed optically thin emission components (the separate components are shown by the fainter dotted lines) and a narrow Gaussian line, as detailed in the text and Table 2. The model lines are from the fit with the emission parameters tied between the EPIC and XRT spectra; only the absorbing column was allowed to differ.
