1. INTRODUCTION
--------------------------------------------------------------------------------
Stellarium is a free GPL software which renders realistic skies in real time
with openGL. It is available for Linux/Unix, Windows and MacOSX. With Stellarium,
you really see what you can see with your eyes, binoculars or a small telescope.
--------------------------------------------------------------------------------
2. INSTALLATION INSTRUCTIONS
--------------------------------------------------------------------------------
Please see the INSTALL file.
--------------------------------------------------------------------------------
3. REQUIREMENT
--------------------------------------------------------------------------------
Windows or linux/POSIX or CYGWIN or MACOSX environment
A 3d openGL acceleration card and a good CPU.
--------------------------------------------------------------------------------
4. QUICK START
--------------------------------------------------------------------------------
Navigation :
Use the direction keys or drag with the mouse to move the point of view.
Use page up and page down keys or mouse wheel to zoom in and out.
Use left mouse button to select an object, right button to select no object and
middle mouse button or SPACE to center on the selected object.
Zooming on nebulas or planets is very interesting....
Use J, K and L to increment/decrement time speed.
Press the H key for more help.
More help can be found on www.stellarium.org, and in the user guide.
--------------------------------------------------------------------------------
5. CONFIGURATION
--------------------------------------------------------------------------------
From version 0.6.0 the most useful configuration options can be set from within
the program.
You can however change it by hand in the file located in config/config.ini on
Windows/MacOSX and in $HOME/.stellarium/ on a unix system.

1. Technical Articles
1.1 The tone reproductor class
The class mainly performs a fast implementation of the algorithm from
the paper [1], with more accurate values from [2]. The blue shift
formula is taken from [3] and combined with the Scotopic vision
formula from [4].

1.2 The skylight class
The class is a fast implementation of the algorithm from the article
"A Practical Analytic Model for Daylight" by A. J. Preetham, Peter
Shirley and Brian Smits.
1.3 The skybright class
The class is a fast reimplementation of the VISLIMIT.BAS basic source
code from Brad Schaefer's article on pages 57-60, May 1998 _Sky &
Telescope_, "To the Visual Limits". The basic sources are available on
the Sky and Telescope web site.

3. Data
3.1 The Hipparcos star catalog
From ESA (European Space Agency) and the Hipparcos mission.
ref. ESA, 1997, The Hipparcos and Tycho Catalogues, ESA SP-1200

3.2 The solar system data mainly comes from IMCCE and partly from Celestia.
3.3 Polynesian constellations are based on diagrams from the Polynesian
Voyaging Society
3.4 Chinese constellations are based on diagrams from the Hong Kong Space Museum
3.5 Egyptian constellations are based on the work of Juan Antonio Belmonte,

3.7 Naval Observatory Merged Astrometric Dataset (NOMAD) version 1
http://www.nofs.navy.mil/nomad
Norbert Zacharias writes:
"There are no fees, both UCAC and NOMAD are freely available
with the only requirement that the source of the data
(U.S. Naval Observatory) and original product name need to be
provided with any distribution, as well as a description about
any changes made to the data, if at all."
The changes made to the data are:
-) try to compute visual magnitude and color from the b,v,r values
-) compute nr_of_measurements = the number of valid b,v,r values
-) throw away or keep stars (depending on magnitude,
nr_of_measurements, combination of flags, tycho2 number)
-) add all stars from hiparcos (incl. component solutions),
and tycho2+1st supplement
-) reorganize the stars in several brigthness levels and triangular
zones according to position and magnitude
The programs that are used to generate the star files are called
"MakeCombinedCatalogue", "ParseHip", "ParseNomad",
and can be found in the util subdirectory in source code.
The position, magnitudes, and proper motions of the stars
coming from NOMAD are unchanged, except for a possible
loss of precision, especially in magnitude. When there is no
v-magnitude, it is estimated from r or b magnitude.
When there is no b- or v- magnitude, the color B-V is estimated from
the other magnitudes.
Also proper motions of faint stars are neglected at all.
