Package astrometry
Blind astrometric calibration of arbitrary astronomical images
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.
Other tools included in the astrometry package can do much more, like
plotting astronomic information over solved images, conversion utilities
or generate statistics from FITS images.
