   +----myStuff.MoonAge
public class MoonAge
extends Object

Variable Index

o DEG_IN_RADIAN
o EIGHTH_OF_MONTH
o PERIOD

Constructor Index

o MoonAge()

Method Index

o daysOld(double)
o flmoon(int, int, JulianDate)
Gives jd (+- 2 min) of phase nph on lunation n; replaces less accurate Numerical Recipes routine.
o lunAge(JulianDate, int)
compute age in days of moon since last new, and lunation of last new moon.
o main(String[])
o moonPhase(JulianDate)
gives the days since last new moon, or New, 1st Qrt, Full, and 3rd Qtr, as appropiate

Variables

o DEG_IN_RADIAN 
  public final static double DEG_IN_RADIAN
o EIGHTH_OF_MONTH 
  public final static double EIGHTH_OF_MONTH
o PERIOD 
  public final static double PERIOD

Constructors

o MoonAge 
  public MoonAge()

Methods

o main 
  public static void main(String args[])
o lunAge 
  public static double lunAge(JulianDate jd,
                              int nlun)
compute age in days of moon since last new, and lunation of last new moon.

o flmoon 
  public static void flmoon(int n,
                            int nph,
                            JulianDate jdout)
Gives jd (+- 2 min) of phase nph on lunation n; replaces less accurate Numerical Recipes routine. This routine implements formulae found in Jean Meeus' *Astronomical Formulae for Calculators*, 2nd edition, Willman-Bell. A very useful book!!

n, nph lunation and phase; nph = 0 new, 1 1st, 2 full, 3 last jdout jd of requested phase

o daysOld 
  public static int daysOld(double age)
o moonPhase 
  public static String moonPhase(JulianDate jd)
gives the days since last new moon, or New, 1st Qrt, Full, and 3rd Qtr, as appropiate
