Resolve spectrum from the entire central pointing (black data points) fitted with a single temperature velocity broadened CIE model without accounting for resonant scattering (BAPEC; red) and with accounting resonant scattering (RSAPEC; blue). Line flux of optically thick Fe xxv w line is suppressed by a factor of ∼14%.
