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. + Contents: .. toctree:: :maxdepth: 2 + + wcsutil + updatewcs + Indices and tables ================== -- cgit
