Class Summary
AbstractRegion AbstractRegion is an abstract class which defines regions on the celestial sphere.
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.
CircularRegion CircularRegion is a circular region on the sky, defined by its center and a radius.
Converter This class, tightly connected to the Unit class, gathers non-standard unit conversions.
ConvexRegion Convex Target (e.g.
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.
EllipticalRegion Elliptical region on the sky, defined by its center + semi-major axes.
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.
PourFrancois  
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.
Region Region is a Factory which implements the AbstractRegion and the constructors of the various regions.
Sptype Spectral type
Supergal The Supergalactic frame is defined such (0,0) represents the direction toward the center of the Local Group of galaxies.
