Enclosing class:

VizierStarParser

public static final class VizierStarParser.HipparchosUcac2
extends Object

This class compares the hipparchos main catalogue with the UCAC2 catalogue. It goes through all HIP numbers, retrieves the color and magnitude information from this catalog and then tries to find a similar entry in the UCAC2 catalog. If an entry is found at a distance not more than 0.001 degrees, it is considered a match. If the UCAC2 catalogue entry has the J and K color specified, output is produced giving Vmag, B-V, UCmag, Jmag, and Kmag. This can then be utilized to find a emphirical expression for Vmag out of UCmag, J&K.
