  • Separately for each camera Cleaning of bad pixels and columns using calibration information user defined Subtract OoT events (pn only) Make images, exposure maps and masks; several energy bands in one go Smooth images (Gaussian) with masks M. Ehle & Rosemary Willatt (ESAC) April 2007
  • Slide 7
  • Combining images from all cameras Make combined exposure map and mask Weight pn against MOS cameras in each band Use images, exposure maps and masks to combine images from all cameras M. Ehle & Rosemary Willatt (ESAC) April 2007
