Constructor Detail

GlieseCatalog

GlieseCatalog(double radius)
        throws java.lang.InterruptedException

The designated constructor for instances of this class. Returns an instance of the interpreted Gliese Catalog which contains all known stars out to the maximum given radius from Sol.

Parameters:

radius - The maximum radius from Sol to which stars are to be included.

Throws:

java.lang.InterruptedException - If access to the catalog data file is interrupted mid-read.

Method Detail

get

public GlieseLine get(int index)

numofStars

public int numofStars()

getLines

public java.util.Vector getLines()

createWorkerThread

private void createWorkerThread()

openGliese

private void openGliese(java.lang.String name)

parseLine

private void parseLine(java.lang.String str)

resolveName

private final void resolveName(char[] cbuf,
                               int source)

Function to try and resolve a name for the star. This may get called numerous times during the reading of a line, so a value system has been imposed on the possible names in order to try and get some sort of consistently "nice" output. The value ranking, from least to most desirable, is as follows (ties are broken in favour of the first element listed): - No name (E.g. NN 12345) -- We don't really want invented names in a "realistic" list -(tie_1) LHS catalog -- Much the same reasoning, the numbers are more interesting, but... -(tie_1) UGPMF catalog -- An ugly collection of letters, the lowest of the low - LP catalog == The lowest of the low in a previous version (v1.4) of this class. -(tie_2) LHS catalog -- The second lowest catalog in version 1.4 -(tie_2) W (or white dwarf) catalog -- White dwarfs might be interesting. -(tie_3) DM catalog -- The Durchmusterung is a known catalog, plus the numbers are interesting -(tie_3) Giclas catalog -- probably not a well known catalog, but it's pronouncable -(tie_4) Gliese and Gliese/Jahreiss catalogs -- pronouncable names, a good comprimise level -(tie_4) HD catalog -- the is probably the best known of the listed catalogs -(tie_5) Vyssotsky catalog -- probably obscure, but I like the name -(tie_5) Wooley catalog -- There don't appear to be many of these, let 'em shine, says I. -(tie_6) Wolf catalog -- It's a known catalog (E.g. Wolf 359 of _Star Trek_ fame) -(tie_6) Ross catalog -- Again, it's a pronouncable name. -(tie_6) Luyten catalog -- Yet another pronouncable name. - Constellation names (e.g. Alpha Centauri) -- If people will think they recognize it, good.
