Region mapping for TweakReg
drizzlepac.mapreg Module
This module provides functions for mapping DS9 region files given in sky coordinates to DS9 region files specified in image coordinates of multiple images using the WCS information from the images.
MapReg() provides an automated interface for
converting a region file to the image coordinate system (CS) of multiple
images (and their extensions) using WCS information from the image(s)
header(s). This conversion does not take into account pointing errors and,
therefore, an examination and adjustment (if required) of output region
files is highly recommended. This task is designed to simplify the creation
of the exclusions and/or inclusions region files used with
TweakReg() task for sources finding.
