Create a simulated copy of 'mymod' with a 100 count source added at position +2,-4

 > imsim sim model=mymod
 Using model quality array...
 Model is exposure corrected, scaling up by exposure of 23212.4 seconds
 Normalising model...
 Model contains 16266.1 counts
 BACK - Background counts /!/ > 16266
 SOURCEC - Number of counts per source /!/ > 100
 SOURCEP - Source positions /[0,0]/ > 2,-4
 WIDTHS - Width of gaussian for psf convolution /0/ >
 SRADIUS - Half width of psf in pixels /15/ >
 ...
 PSF - Choose PSF for simulated sources /'ANALYTIC'/ > XRT_PSPC
 MASK - PSPC psf option (LIST for descriptions) /'VARPROFILE'/ >
 Loaded XRT psf cube with 10 energy channels
 AUX - Mean photon energy in KeV > 0.6
 Background 8051 counts
 Source 1 95 counts
Create a 5 simulated copies of 'mymod' with a specified Log N Log S distribution.
 > imsim nfile=5 out=sim model=mymod

 as before
 ...
 LOGNS - Choose source counts using Log NS /NO/ > y
 SNORM - Normalisation flux > 400
 NSNORM - Number of sources with flux >= SNORM/degree**2 > 10
 ED - Index of Log NS for flux 1.5
 EU - Index of Log NS for flux>SB > 1.2
