pnspec
read an EPIC pn SciSim FITS file (generated by running podf on the output of SciSim), reconstruct the split events, and return the correct EPIC pn spectrum

readpn,spectrum,rawspectrum=rawspectrum,auxfile=auxfile, $ pnfile=pnfile,chatty=chatty,exposure=exposure
auxfile: file containing the auxilliary information (usually called pn_aux.fits pnfile : file containing the CCD events (e.g., pn_ccd1.fits)
chatty : if set, give some debugging information nosplitcorr : if set, no split-event correction is performed timemode : if set, the simulation used the Timingmode, default is the imaging mode.
spectrum: the binned spectrum (photons/channel)
rawspectrum: the binned spectrum, uncorrected for splits rawx: the x-coordinates of the events rawy: the y-coordinates of the events exposure: exposure time of the observation
none
* For the purpose of this subroutine, ``Split events'' are defined as all those events happening simultaneously (=in the same time frame) AND within 1 pixel to each other. No effort is taken to account for split events where more than two pixels contribute. Beware in the case of bright sources, where more than photon might get detected during the readout of one frame. These can look like splits
