public class SupplementaryPairMaker

extends Operation

The SupplementaryPairMaker is a class to make pairs between the single (not paired) stars among two lists of stars. From the brightest star to the faintest star, a single star in the first list is getting paired with a single star in the second list. But if the second star has a closer candidate in the first list, it is paired with the closer one. Note that only bright stars, brighter than the specified threshold, are considered.

The search radius is determined based on the magnitude as:

      7 mag : 4'

      9 mag : 2'

     11 mag : 1'

     13 mag : 30"

     15 mag : 15"

 

The upper limit is 3'. The lower limit is 5 pixels.

The (x,y) position and magnitude of stars in the both lists must be set properly. The two lists are sorted in the constructor.
