FULL REFERENCES & CREDITS -------------------------------------------------------------------------------- 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].

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".

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 http://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 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, Instituto de Astrofisica de Canarias 3.6 The Tycho-2 Catalogue of the 2.5 Million Brightest Stars Hog E., Fabricius C., Makarov V.V., Urban S., Corbin T., Wycoff G., Bastian U., Schwekendiek P., Wicenec A. http://cdsweb.u-strasbg.fr/ftp/cats/I/259 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. 4.
