Credits:
We use the US Naval Observatory USNO-SA2.0 catalog
For catalogue acces we use Doug Mink's fine scat program.
Notes:
Unless explicitly specified, we use R-band magnitudes.
The "selection criteria" option changes the star selection strategy:
  • all gives back all stars
  • Nearest gives the nearest star only
  • Brightest gives the brightest star
  • Weighted gives the star with the highest value of a score proportional to the inverse of the distance and to the magnitude (nearer and brighter => better).
