The HRMA raytrace simulation was submitted to ChaRT using the spectrum file "NGC2362_flux_chart.dat" for 98 ksec; an off-axis angle of 0.359 arcmin; and azimuthal angle of 30.659 deg. We will shorten the returned file name to just "HRMA.fits". (a) note that rt_y and rt_z are in units of millimeters on the focal-plane using the spacecraft y- and z-axes. % dmcopy infile="HRMA.fits[opt type=i4][bin rt_y=0.2946265:1.5178615:#51,rt_z=-1.1453025:0.0779325:#51]" outfile="hrma_51x51.img" using these rt_y and rt_z ranges to create a 51x51 pixel image, the subsequent pixel scale is equivalent to one ACIS pixel (ACIS platescale is 23.985 microns per pixel).
