Reverb.disk_type

Setting for how photons generated in the disk are treated when generating path distributions for wind cells.

Type

Enumerator

Values
correlated

This mode assumes that disk emission is correlated with the central source. Photons generated in the disk start with a delay equal to the direct distance to the central source. This assumes that the ionisation state and luminosity of the disk surface layer is mostly determined by unscattered photons from the central source.

uncorrelated

This mode generates photons with a delay of 0 wherever in the disk they come from. This mode is of slightly questionable use and should be ignored in preference to 0 or 2. It will, in practise, generally work out similar to type 0 as most of the UV photons are generated close-in to the CO.

ignore

This mode assumes that disk photons do not correlate with the central source (i.e. disk surface ionisation state and emissivity is driven not by irradiation from the CO but by the mass inflow). This means that whilst they contribute to heating the wind, they do not strongly contribute to the lags for a given line. Photons generated by the disk do not contribute to the path distributions in the wind in this mode.

By removing the (generally) short-delay disk photons from the wind path distributions, this will slightly bias them towards the longer delays associated with wind self-heating/excitation.
