Class Summary 
Astrocoo 
This class defines the spherical coordinates used in Astronomy. 
Astroformat 
This class contains definitions used in Parsing and Editing of numbers,
and the default representation of the NaN (null) value. 
Astroframe 
This abstract class defines the required methods to instanciate the
definition of a frame used for astronomical coordinates. 
AstroMath 
Trigonometric and a few other functions used in the astronomical context. 
Astropos 
The class Astropos adds to Astrocoo the notions
of mouvement (proper motions, velocity) and error ellipses. 
Astrotime 
The astronomical time may be expressed in (Modified) Julian Days,
Julian Years or Besselian years. 
Converter 
This class, tightly connected to the Unit class,
gathers nonstandard unit conversions. 
Coo 
Class that manipulates the coordinates defining a point on the
celestial sphere. 
Coocube 
The routines provided in this module define a "coordinate" as
a face number (between 1 and 6), and two (X,Y) values
in the range [1,1[ representing the projection of a direction onto
a cube. 
Ecliptic 
The ecliptic frame is defined such that the Sun has a latitude = 0. 
Editing 
Class for 'nice' edition of numbers. 
Equatorial 
This abstract class introduces the specificities of the equatorial
coordinates. 
FK4 
The FK4 is an equatorial coordinate system (coordinate system linked to
the Earth) based on its B1950 position. 
FK5 
The FK5 is an equatorial coordinate system (coordinate system linked to
the Earth) based on its J2000 position. 
Galactic 
The Galactic frame is defined such that the plane of our Galaxy
(the Milky Way) has a latitude close to zero. 
ICRS 
The ICRS frame (International Celestial Reference System) is defined
by the Hipparcos mission. 
Mtype 

Otype 
The Otype is a classification of the astronomical objects
in a hierarchical structure. 
Parsing 
This class interprets text and is able to convert to numbers,
or find a symbol in a list of symbols. 
Proj3 
Class defining the Mathematical Projections of the Celestial Sphere. 
Qbox 
The Qbox divides the celestial sphere into "cells" of approximative
constant size. 
QboxNumber 
The QboxNumber is just a number representing a cell
of the celestial sphere. 
Supergal 
The Supergalactic frame is defined such (0,0) represents the direction
toward the center of the Local Group of galaxies. 
Unit 
Class able to deal with scientific units and make the appropriate
conversions.
