Dust::MMPUV::MMPUV | ( | double | chi | ) |
These are the methods for the MMPUV class.
Returns the radiation field of Mezger, Mathis and Panagia ( 1982A&A...105..372M ) as ammended in the 1983 paper. chi controls the scaling of the field.

The Specific Energy density. E must be specified in the units of Joules (using SI throughout). More precisely this is energy per unit volume per unit energy interval. At some time I convinced my self that this is equivalent to the (number of photons) m^-3, but not sure any more. Anyway, u_E dE than has the units of J m^-3. Conversion to flux can be done using the speed of light. (inerited from UnaryDD)
