Comments

• The PSF is used at 1.5 keV in all bands. This is thought to be more accurate than taking the central energy of each band.
• Subimages overlap by several arcminutes and a good fraction of the sources will be "detected" twice.
• The detection likelihoods have been set to a compromise between excluding real sources and including too many statistical fluctuations.
