bbodyrad: blackbody spectrum, area normalized

A blackbody spectrum with normalization proportional to the surface area.

$\displaystyle A(E) = {{K \times 1.0344 \times 10^{-3} E^2 dE}\over{\exp(E/kT)-1}} $

where

par1= kT temperature keV
norm= K $R_{km}^2/D_{10}^2$, where $R_{km}$ is the source radius in km and $D_{10}$ is the distance to the source in units of 10 kpc.
