The program works with the data received in Full & Restricted Imaging modes. With the use of the position mapping tables (see Appendix B.4) j_cor_position converts detector positions corrected for microstrip plate irregularities into absolute values.
This component also determines whether there are hotspots on the microstrip plate and flags all the events orginating in hotspot areas so that these events can be ignored by the rest of the science analysis. It also flags dubious events coming from dead anodes, inactive areas around the detector and areas around the calibration areas.
See Appendix C.1 for the description of j_correction output.
