Pysofa provides a Python interface to the the IAU-sanctioned Standards of Fundamental Astronomy (SOFA) library. SOFA is a set of algorithms and procedures that implement standard models used in fundamental astronomy, covering:
- Calendars
- Time Scales
- Earth rotation and sidereal time
- Ephemerides (medium precision)
- Geocentric/geodetic transformations
- Precession, nutation, polar motion
- Star space motion ...

Snippet: Fix the WCS for a FITS image file
The code snippet which follows will allow you to fix an error in the astrometry of a FITS image. This is especially common with HST images because the astrometrical errors can be an arcsecond or more. The method used assumes that you have extracted the positions (RA, Dec) for at least 2 image point sources for which you have more accurate reference positions (e.g. from SDSS or ...
