notch: absorption line, notch

A notch line absorption. This is model is equivalent to a very saturated absorption line.


\begin{displaymath}
M(E) = \begin{array}{ll}
(1-f) & E_L - W/2 < E < E_L + W/2 \\ [.2cm]
1 & \mbox{elsewhere}
\end{array}\end{displaymath}

where

par1=$E_L$ line energy (keV)
par2=W line width (keV)
par3=f covering fraction
