pixtopix - task to convert pixel positions from an input image to pixel positions in an output WCS or image
""" STWCS
This package provides support for WCS based distortion models and coordinate
transformation. It relies on astropy.wcs (based on WCSLIB). It consists of
two subpackages: updatewcs and wcsutil.
updatewcs performs corrections to the basic WCS and includes other distortion
infomation in the science files as header keywords or file extensions.
Wcsutil provides an HSTWCS object which extends astropy.wcs.WCS object and
provides HST instrument specific information as well as methods for coordinate
transformation. wcsutil also provides functions for manipulating alternate WCS
descriptions in the headers.
