Workspace Method psdModifiedGammaMassXmean


Modified gamma distribution PSD, with mass content and mean size
(Xmean) as inputs.

"Mean size" is here defined as mass weighted size. Remembering that
mass is a*x^b, this mean size can be expressed as M_b+1/M_b where M_b
is b:th moment of the PSD (see e.g. Eq. 17 in Petty&Huang, JAS, 2011).

This version of MGD PSD works as psdModifiedGammaMass, but takes
mass content and mass size as first two arguments. This means that
the first and second column of pnd_agenda_input shall hold mass
content and Xmean, respectively. Accordingly, the number of dependent
parameters is two.

These requirements apply to the MGD parameters:
  mu + scat_species_b + 1 > 0
  la > 0
  ga > 0
  Xmean must be > 0.
