A convolution model to calculate the flux of other model components. For example :
suppose the model is :
phabs*(pow + gauss)
then
cflux*phabs*(pow + gauss)
with the normalizaton of the power-law model fixed gives the flux and error on the entire model.
phabs*cflux*(pow + gauss)
again with the normalization of the power-law fixed gives the unabsorbed flux and error. Finally,
phabs*(pow + cflux*gauss)
with the normalizaton of the gaussian fixed gives the flux and error on the gaussian component. It is important to ensure that the energy range over which the model is calculated (which is determined by the response matrix in use) covers the energy range for which the flux is calculated.
Parameters are :
|
par1= Emin |
Minimum energy over which flux is calculated. |
|
par2= Emax |
Maximum energy over which flux is calculated. |
|
par3=lg10Flux |
log (base 10) flux in erg/cm2/s |
