highecut, zhighect: high-energy cutoff

A high energy cutoff.


\begin{displaymath}
M(E) = \begin{array}{ll}
exp\left[(E_c-E)/E_f\right] & E \geq E_c\\ [.2cm]
1.0 & E \leq E_c
\end{array}\end{displaymath}

where

par1=$E_c$ cutoff energy in keV
par2=$E_f$ e-folding energy in keV

The redshifted version zhighect has

\begin{displaymath}
M(E) = \begin{array}{ll}
exp\left[(E_c-E[1+z])/E_f\right] & E \geq E_c\\ [.2cm]
1.0 & E \leq E_c
\end{array}\end{displaymath}

where

par1=$E_c$ cutoff energy in keV
par2=$E_f$ e-folding energy in keV
par3=z redshift
