The astrometry engine will take any image and return the astrometry world coordinate system (WCS), a standards-based description of the transformation between image coordinates and sky coordinates.

This package installs the 4107 index file from the Tycho-2 catalog containing skymarks of sizes 22 arcminutes to 30 arcminutes.
