Dust::RadField::~RadField | ( | ) | [virtual] |
This class has virtual methods -- should also have a virtual destructor !
virtual double Dust::RadField::operator() | ( | double | E | ) | [pure virtual] |
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)
Implemented in Dust::BBRadField, Dust::MMPUV, and Dust::ThinShell.
double Dust::RadField::Edens | ( | void | ) |
Returns the specific energy by integrating the differential energy density between the cutlow and cuthigh limits.
double Dust::RadField::Edens | ( | double | elow_J, | |
double | ehigh_J | |||
) |
Returns the specific energy density between supplied limits.
