* McXtrace, x-ray tracing package
* Copyright, All rights reserved
* DTU Physics, Kgs. Lyngby, Denmark
* Synchrotron SOLEIL, Saint-Aubin, France
*
* Component: EPSD_monitor
*
* %Identification
* Written by: Erik B Knudsen
* Date: June 22, 2009
* Release: McXtrace 1.5
* Origin: DTU
*
* Position-energy-sensitive monitor.
*
* %Description
* An nx times ny pixel energy resolved PSD monitor, which only counts photons with energy in an interval
* given by Emin and Emax in nE energy bins. The default energy interval is (almost) infinite, with a single bin.
* If nE>1 the component will output nE detector files + one which is integrated over the full energy interval.
*
* Example: EPSD_monitor(xwidth=0.1, yheight=0.1,
* nx=90, ny=90, filename="Output.psd")
*
* %Parameters
* INPUT PARAMETERS:
*
* Emin: [keV] Lower bound of energy interval.
* Emax: [keV] Upper bound of energy interval.
* xwidth: [m] Width of detector.
* yheight: [m] Height of detector.
* nx: [1] Number of pixel columns.
* ny: [1] Number of pixel rows.
* nE: [1] Number of energy bins.
* filename: [str] Name of file in which to store the detector image.
* restore_xray: [1] If set, the monitor does not influence the xray state.
* nowritefile: [1] If set, monitor will skip writing to disk
*
