Output

The main output is a FITS file containing the radial profile, the theoretical PSF at that position in the image and at that energy and the best fit normalisation of that PSF to the actual radial profile data.

The data columns are:

• RAD_LO: The start of the radial bin (arcsec)
• RAD_HI: The end of the radial bin (arcsec)
• RPROF: The radial profile in units of counts per arcsec**2
• RPROF_ERR: The error on the radial profile
• RPSF: The nominal point spread function
• FIT_RPSF: The PSF after fitting to the radial profile
