Actually, it appears he may not be. This page on the NGC/IC website: http://www.klima-luft.de/steinicke/ngcic/rev2000/Explan.htm says: "The data of my Revised New General Catalogue and Index Catalogue are used by Mathematica, TheSky, Guide, SkyMapPro, Starry Night, Eye&Telescope, the SAC database and the database of the Losmandy mounting" If as this claims SAC contains data from NGC/IC then SAC would be required to follow the license terms of NGC/IC, and the person running SAC cannot relicense that data without the permission of NGC/IC. From this page: http://www.klima-luft.de/steinicke/ngcic/ngcic_e.htm we get: "Any non-commercial use of my data is free! If a commercial use is planned, please contact me!" This would appear to make it impossible to include NGC/IC in Fedora, and that would also apply to any derivative works like SAC. [Note that Sky & Telescope also appears to use this data, which may be an indication as to why they are unable to relicense their product] _______________________________________________ Fedora astronomy mailing list [email protected] http://fedoraproject.org/wiki/SIGs/Astronomy https://admin.fedoraproject.org/mailman/listinfo/astronomy
