            bbody, zbbody:  blackbody

A blackbody spectrum.

 

A(E) = K*8.0525*E^2*dE/((kT)^4(exp(E/(kT))-1))

where

par1= kT

temperature keV

norm= K

L_39/D_10^2, where L_39 is the source luminosity in units of 1039 ergs-1 , D10 is the distance to the source in units of 10 kpc

 

 

The zbbody variant allows an additional (fixed) redshift parameter

A(E) = 8.0525K[E(1+z)]^2*dE/((1+z)kT^4*(exp[E(1+z)/kT]-1))

where

par1= kT

temperature keV

z

Fixed redshift

norm= K

L_39/[D_10(1+z)]^2, where L_39 is the source luminosity in units of 1039 ergs-1 , D10 is the distance to the source in units of 10 kpc
