Regions

Spatial regions may be entered in raw chip, detector, sky (X/Y) or celestial (RA, DEC, FK4 2000) coordinates. If raw coordinates are used the CCD must be given using the parameter ccdno. If the coordinates of the region are not the same as those of the image, e.g. a sky pixel region on a detector coordinate image, then the task will still function but will run more slowly. An error will result if the spatial region is not within the image. Any shape conforming to the selectlib rules may be used, except that RAW coordinates may currently only be entered using a circular selection.
