XWINDFE model parameters
| Parameter | Description | Units |
|---|---|---|
| log10ṁw | Wind mass outflow rate | Ṁw/ṀEdd |
| rin | Inner launch radius (see Fig. 1) | RG |
| rout | Outer launch radius | RG |
| df | Distance from origin to wind focus (see Fig. 1) | RG |
| fcov | Wind covering fraction as seen from the central black hole |  |
| log10v∞ | Outflow velocity at infinity (see Eqn. 6) | c |
| rv | Velocity scale length. The distance along the streamline where the wind reaches half of v∞ | RG |
| β | Wind velocity exponent. Determines the acceleration of the wind (see Eqn. 6) | Dimensionless |
| vturb | Turbulent velocity. Assumed constant across the wind. Sets the width of the Gaussian smoothing kernel used to emulate turbulence. | km/s |
| κ | Sets the weighting for the wind launch efficiency as a function of radius. Larger values will weigh the mass-outflow towards larger radii (and vice-versa for lower values). See Eqn. 8 | Dimensionless |
| Inc. | Observer inclination, measured from the z-axis | degrees |
| AFe | Iron abundance, relative to solar. Uses the abundance values from (Anders & Grevesse 1989) | [Fe]/[Fe⊙] |
| N0 | Normalisation of the incident X-ray power-law emission | photons s−1 cm−2 at 1 keV |
| Γ | Photon index of the incident X-ray power-law spectrum | Dimensionless |
