Modified gamma distribution (MGD) PSD, with mass content as input.

See psdModifiedGamma() for a defintion of MGD parameters and how this PSD is handled in ARTS. Only deviations with respect to psdModifiedGamma() are described here.

This version of MGD PSD takes mass content as first input argument. This means that the first column of pnd_agenda_input shall hold mass content data.

The mass content basically replaces one of the standard parameters (n0, mu, la and ga). This parameter is denoted as the dependent one. The dependent parameter is selected by setting the corresponding GIN to -999. So far only n0 and la are allowed to be dependent.

Regarding remaining columns in pnd_agenda_input and constant parameter values (by GIN) follows the same principle as for psdModifiedGamma() except that mass is always in column one (as mentioned) and that there is no position in pnd_agenda_input for the dependent parameter.

These requirements apply to the MGD parameters:

  1. mu + scat_species_b + 1 > 0

  2. la > 0

  3. ga > 0

  4. If la is the dependent parameter, mass content must be > 0.
