rgsevents adds the EVENTS and REJPIXn tables to the intermediate event lists along with an index of event associations in the PIXELS table. Multiple pixel events are recombined and the event centroid positions are computed. These positions are given in so-called “hardware” coordinates, which must be corrected for aspect drift before they can be used for spectral analysis. Various other event properties, such as contamination from bad pixels, are noted in the FLAG column. The REJPIXn tables contain the lists of pixels not already indicated in the BADPIXn tables that might later need to be excluded from the exposure maps.
