Follow-up Comment #2, task #13557 (project gnuastro):
The IVOA MOC <http://www.ivoa.net/documents/MOC/> (Multi-Order Coverage map)
standard is also apparently a good way to efficiently find overlaps between
images on the Sky for this task. We should look into it.
Maybe the table doesn't have to be raw WCS information, but instead use the
HEALPix sky tessellation algorithm for making the coverage of each image on
the celestial sphere.
