The formula and parameters for the redshifted variant are:
![\begin{displaymath}
A(E) = \left\{ \begin{array}{ll}
K [E(1+z)]^{-\Gamma_1} & \...
...} &
\mbox{if $[E(1+z)] > E_{break}$} \\
\end{array} \right.
\end{displaymath}](img170.png)
where:
par1 = ![]() |
power law photon index for ![]() |
par2 = ![]() |
break point for the energy in keV |
par3 = ![]() |
power law photon index for ![]() |
par4 = ![]() |

norm = K | photons/keV/cm![]() |
If POW_EMIN and POW_EMAX have been defined by the xset command then
the norm becomes the flux in units of ergs/cm
/s over the
energy range (POW_EMIN, POW_EMAX) keV unless POW_EMIN = POW_EMAX in
which case the norm becomes the flux density in micro-Jansky at
POW_EMIN keV. In these cases it is important that POW_EMIN and
POW_EMAX lie within the energy range on which the model is being
evaluated.
