Class Summary

Class	Description
Astro	Useful constants
AstroDate	A support class for DateOps.
AstroOps	AstroOps is a 'catch-all' class that performs some useful calculation functions that didn't fit anywhere else.
AstroTest
AtlasRef	AtlasRef is a class that figures out which page in a number of atlases best show the given RA and Dec.
DarkCal	A command-line program to determine the darkest hours for a given location & month.
DarkCalCalc	A class to calculate and store DarkCal data, and optionally cache the data to a file.
DarkCalData	A simple struct-style class to store DarkCal data
DarkCalInput	A simple struct-style class to hold date & observer location.
DarkCalProp	Properties file support for DarkCal
DateOps	A class to perform calendrical conversions.
Latitude	A simple class to create a type-safe Latitude
LocationElements	This is a convenience class used for passing around polar coordinates.
Longitude	A simple class to create a type-safe Longitude
Lunar	A class that can calculate lunar fundmentals for any reasonable time.
LunarCalc	LunarCalc is a class that does lunar calculations that do not directly depend on the lunar fundamentals (although some do need to call functions in Lunar).
LunarTerms	Holds a large quantity of constant data terms for class Lunar.
MathOps	MathOps contains some useful trig, vector and matrix operations.
Nutation	Nutation functions and static data.
ObsInfo	Holds latitude, longitude and time zone of an observing location.
PlanetData	This class handles planetary motion calculations and conversions.
Planets	A common place to store planetary constants.
Pluto	A class that can calculate the orbit of Pluto.
Pluto2
RiseSet	Calculates rise & set times of the sun or moon, and also calculates twilight times (civil/nautical/astronomical).
TimeOps	TimeOps contains miscellaneous time-related functions.
TimePair	A simple class used to store a pair of times.
VisLimit	Calculates sky brightness and limiting magnitude.
VisLimitAngularBrightnessData	A support class for VisLimit.
VisLimitFixedBrightnessData	A support class for VisLimit.
Vsop	This class wraps the VSOP87 data and provides VSOP planetary position calculation functions for Mercury through Neptune (VSOP doesn't handle the moon or Pluto).
VsopData	All the static VSOP data, in a separate file for managability.

Exception Summary

Exception	Description
NoInitException	NoInitException is thrown if the caller attempts to call a method which requires some sort of initializtion if init was not done.
ValueException	ValueException is thrown if the caller attempts to pass in an invalid value, or the results of a calculation generate an invalid value.
