From top to bottom, IGR J1719, IGR J1509, and XSS J0056. RGS1 data and model (black), RGS2 data and model (blue). The models use the EPIC best-fit values. Those for IGR J1719 and IGR J1509 also include fitting for gsmoothσ and for mekal density parameters. Top panel inset shows the OVII line wavelength range (20.6−23.1 Å) with the EPIC best-fit low density mekal (black), the high density, narrow mekal (blue) and the high density, gsmooth broadened meakl (red). For XSS J0056 we show the EPIC best-fit model with (black) and without (red) the edge.
