astro.TychoCatalog

public class TychoCatalog
extends Object

Reads in the Tycho2 Star Catalog (Hog et al, A&A 355, L27). If V or B-V is not given, the tycho magnitudes B_T and V_T are used to construct a

 V=VT-0.09*(BT-VT)

    B-V=0.85*(BT-VT)
 

This catalog is too big for entire serialization, thus we read it in, apply a filter and serializes the remainder.
