""" STWCS
This package provides support for WCS based distortion models and coordinate
transformation. It relies on PyWCS (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 pywcs.WCS object and provides HST instrument
specific information as well as methods for coordinate tarnsformaiton. Wcsutil also provides
functions for manipulating alternate WCS descriptions in the headers.
