190	! 2 for exponential distribution,
191	! 3 for power law distribution,
192	! 4 for monodisperse distribution,
193	! 5 for lognormal distribution.
194
195	! PHASE - Set to 0 for liquid, 1 for ice.
196
197	! DMIN - The minimum drop size for this class (micron), ignored for monodisperse.
198	! DMAX - The maximum drop size for this class (micron), ignored for monodisperse.
199	! Important note: The settings for DMIN and DMAX are
200	! ignored in the current version for all distributions except for power
201	! law. Except when the power law distribution is used, particle size
202	! is fixed to vary from zero to infinity, a restriction that is expected
203	! to be lifted in future versions. A placeholder must still be specified
204	! for each.
205
206	! Density of particles is given by apm*D^bpm or a fixed value rho. ONLY specify ONE of these two!!
207	! APM - The alpha_m coefficient in equation (1) (kg m**-beta_m )
208	! BPM - The beta_m coefficient in equation (1), see section 4.1.
209
210	! RHO - Hydrometeor density (kg m-3 ).
211
212	! P1, P2, P3 - are default distribution parameters that depend on the type
213	! of distribution (see quickmbeam documentation for more information)
214	!
215	! Modified Gamma (must set P3 and one of P1 or P2)
216	! P1 - Set to the total particle number concentration Nt /rho_a (kg-1 ), where
217	! rho_a is the density of air in the radar volume.
218	! P2 - Set to the particle mean diameter D (micron).
219	! P3 - Set to the distribution width nu.
220	!
221	! Exponetial (set one of)
222	! P1 - Set to a constant intercept parameter N0 (m-4).
223	! P2 - Set to a constant lambda (micron-1).
224	!
225	! Power Law
226	! P1 - Set this to the value of a constant power law parameter br
227	!
228	! Monodisperse
229	! P1 - Set to a constant diameter D0 (micron) = Re.
230	!
231	! Log-normal (must set P3 and one of P1 or P2)
232	! P1 - Set to the total particle number concentration Nt /rho_a (kg-1 )
