These transformations map the pixel locations in an image to their real-world units, such as their position on the sky sphere. It performs three separate classes of WCS transformations: - Core WCS, as defined in the `FITS WCS standard`_, based on Mark Calabretta's `wcslib`_. See `~astropy.wcs.Wcsprm`. - Simple Imaging Polynomial (`SIP`_) convention. See `~astropy.wcs.Sip`. - table lookup distortions as defined in WCS `distortion paper`_. See `~astropy.wcs.DistortionLookupTable`. Each of these transformations can be used independently or together in a standard pipeline. é)Ú*)ÚInvalidTabularParametersError)ÚutilscCsddl}|j |j t¡d¡S)z7 Get the path to astropy.wcs's C header files. éNZinclude)ÚosÚpathÚjoinÚdirnameÚ__file__)r©r ú3lib/python3.9/site-packages/astropy/wcs/__init__.pyÚ get_includesr N)Ú__doc__ZwcsrÚrr r r r r Ús
