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”)

Energy-selective PSD monitor
The EPSD_monitor closely resembles PSD_monitor with the difference that this component may be given an energy interval: \(\left [E_{min},E_{max}\right ]\), in which it is sensitive. Photon rays falling within this interval are detected, those outside are ignored.
The output from EPSD_monitor is the integrated counts, \(n, I, M_2\), as well as three two-dimensional arrays of counts: \(n(x,y), I(x,y), M_2(x,y)\). The arrays are written to a file, filename, and can be read e.g. by the tool mxplot, see the system manual.
