The files describe the PSFs of the flight mirror modules xrt1, xrt2 or xrt3 vs field angle, energy and field azimuth. The xrt1, xrt2 or xrt3 telescopes are respectively associated with the MOS1, MOS2 and PN EPIC cameras. Each file will consist of a header, a table section and an image section.
Note: Inversion due to the mirroring effect of the gratings takes place as part of the CAL function CAL_rgsgetXRTFigure (see section 3.4.33).
