lsmooth: lorentzian smoothing

Lorentzian smoothing with a variable width, which varies as the par2 power of the energy. The width at 6 keV is set with par1.


\begin{displaymath}
\begin{array}{ll}
dC(E) = & \frac{\Sigma(E)}{2\pi[(E-X)^2+(\...
...}A(X)d(X)\\ [.2cm]
\Sigma(E) = & \sigma(E/6)^\alpha
\end{array}\end{displaymath}

where:

par1=$\sigma$ lorentzian sigma at 6 keV
par2=$\alpha$ power of energy for sigma variation
