Hi, The UCAC3 files for CdC are now ready for download. You can get them from: http://www.ap-i.net/skychart/en/download_catalogs or directly: https://sourceforge.net/projects/skychart/files/2-catalogs/Stars/UCAC3/
The catalog is split in three part so you can get only the zone visible from your area. ucac3-catalog-south.zip : South zone -90 to -30 ucac3-catalog-equator.zip : Equatorial zone -30 to +22.5 ucac3-catalog-north.zip : North zone +22.5 to +90 A fourth file ucac3-index.zip contain the optional full search index for all the zones. Each file is about 500MB is size. Extract all this zip under ciel\cat or share/skychart/cat. As each file is autonomous there is two common file on each, when prompted for replacement you can respond yes or no without effect. The information for each star include: identifier, RA, Dec, aperture magnitude, proper motion, approximate color index. I finally not upload the smaller version with less information. Because of a good compression factor on the full version the size difference was not so big (about x1.5) and if you can download 300MB you can also download 500MB. Remember to install and activate Tycho2 at the same time for the bright stars. My preferred star catalog setting for general use is now: BSC 0 - 10 (0 - 360) Tycho2 0 - 6 (0 - 45) 3UC 0 - 3 (0 - 5) Patrick
