* Processing speed: limited by the I/O performances of the machine (typically 50 Mpixel/s on a workstation), * Ability to work with very large images (up to, say, 10^8 × 10^9 pixels on a 64 bit system), * FITS format (including Multi-Extension) is used for input and 3/5⤵

output. Output flag-map format selection is automatic (8, 16 or 32bits), * Up to 30 weight-maps, 30 flag-maps, and thousands of polygons can be handled simultaneously. * Automatic rasterizing of DS9 .reg files, * Statistics of flagged and weighted areas, 4/5⤵
