Output Files

1. event file with modified/additional items:
   • filled in columns FLAG, PHA and PI (for PRODUCT: EPIC event list)
   • modified columns ENERGYE1, ENERGYE2, ENERGYE3 and ENERGYE4 if useccfdarkframe=Y
   • XMMEA_nn keywords detailing which flags were set
   • XMMEA_SM keyword defining selection for spectra
   • keywords detailing which subroutines were activated
   • comment lines with names of input files
   • keywords propagated to the EXPOSURE extension (for evlistcomb)
2. optical background map and time-series over the CCD from E (for calibration purposes) as a separate FITS file with:
   • the background map (real, 600x600) with the offsets added back in, stored in the primary.
   • an array (integer, 600x600) extension (CCD_WGHT) storing the weight (number of pixels contributing) of each pixel
   • a binary table extension (CCD_VAR) for the time-series, with two columns BKGCHARGE (real: average background per time bin, offsets subtracted) and BKGWEIGHT (integer: number of pixels contributing to each time bin).
   • an OFFSETS0 extension propagated from the events file, with the same structure as the offsets file in the ODF ([1]).
