--------------------------------------------------------------------------------1. INTRODUCTION--------------------------------------------------------------------------------Stellarium is a free GPL software which renders realistic s ies in real timewith 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 environmentA 3d openGL acceleration card and a good CPU.

--------------------------------------------------------------------------------

4. QUICK START--------------------------------------------------------------------------------Navigation :Use the direction eys or drag with the mouse to move the point of view.Use page up and page down eys or mouse wheel to zoom in and out.Use left mouse button to select an object, right button to select no object andmiddle 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 ey 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 withinthe program.You can however change it by hand in the file located in config/config.ini onWindows/MacOSX and in $HOME/.stellarium/ on a unix system.

1.1 The tone reproductor classThe class mainly performs a fast implementation of the algorithm

fromthe paper [1], with more accurate values from [2]. The blue

shiftformula is ta en from [3] and combined with the Scotopic visionformula from [4].[1] "Tone Reproduction for Realistic Images", Tumblin and Rushme

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 s ybright classThe class is a fast reimplementation of the VISLIMIT.BAS basic s

3. Data3.1 The Hipparcos star catalog

From ESA (European Space Agency) and the Hipparcos mission.ref. ESA, 1997, The Hipparcos and Tycho Catalogues, ESA SP-1200http://cdsweb.u-strasbg.fr/ftp/cats/I/239

3.2 The solar system data mainly comes from IMCCE and partly from Celestia.

3.3 Polynesian constellations are based on diagrams from the PolynesianVoyaging Society

3.4 Chinese constellations are based on diagrams from the Hong Kong Space Museum

3.5 Egyptian constellations are based on the wor of Juan Antonio Belmonte,

http://www.nofs.navy.mil/nomadNorbert Zacharias writes:"There are no fees, both UCAC and NOMAD are freely availablewith the only requirement that the source of the data(U.S. Naval Observatory) and original product name need to beprovided with any distribution, as well as a description aboutany 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 valu

es-) compute nr_of_measurements = the number of valid b,v,r values-) throw away or eep 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 triangu

larzones according to position and magnitude

The programs that are used to generate the star files are called"Ma eCombinedCatalogue", "ParseHip", "ParseNomad",and can be found in the util subdirectory in source code.The position, magnitudes, and proper motions of the starscoming from NOMAD are unchanged, except for a possibleloss of precision, especially in magnitude. When there is nov-magnitude, it is estimated from r or b magnitude.When there is no b- or v- magnitude, the color B-V is estimated

fromthe other magnitudes.Also proper motions of faint stars are neglected at all.
