Module buildmask

source code

Functions to build mask files for PyDrizzle.

buildMaskImage(rootname,bitvalue,extname='DQ',extver=None): This function takes the DQ array(or array from extension given) and builds a bit mask as an input weighting mask for 'drizzle'.
buildShadowMaskImage(rootname,detnum,replace=no): This function builds a weighting image for use with drizzle from the WFPC2 shadow mask functions derived from 'wmosaic'.
