I have made a new catalog of stars that is based on the BSC-catlog but with updated data and inclusion of info of both double stars and variable stars. The catalog is in two flavours and can be downloaded from:
1) Suitible for with BSC-catalog deactivated in CdC: http://web.telia.com/~u95304762/sbsc/sbsc.zip 2) Suitible for with BSC-catalog activated: http://web.telia.com/~u95304762/sbsc/sbsc2.zip Some of the characteristics is: - Only stars north of decl. -33 (stars visible from Sweden) - Inclusion of all stars with Bayer/Flamsteed/HR-designation - Inclusion of all other stars tht is brighter than 6.5 - Double stars with a combined magnitud of 6.5 or brighter. - Variable stars with a maximum of 6.5 or higher. - Total of 7207 stars. Stars: - Data for position, magnitud, B-V, parallax, spectral class, proper motion is from Sky2000 ver 4. - Bayer/Flamsteed/proper name is from HD-DM-GC-HR-HIP-Bayer-Flamsteed Cross Index. - Alternative Bayer/Flamsteed designation for some stars. Double stars: - For 913 stars, closer than 2 minute of arc and where both components is present in Tycho-2 or Sky2000, a combined magnitud is computed as well as the stars own. Magnitud, separation an position angles is taken from the position in these catalogs, preferably from Tycho-2 - Simpler data for another 1400 double stars from Sky2000. Variables: - Data for 289 variable stars with a maximun magnitud higher than 6.5 and an amplitud more than 0.2 - GCVS designation and type - Max/min magnitud or amplitud. - Period for periodic variables. - Catalog magnitud for variables is an average maximum as observed at AAVSO during last 10-15 years. - For less studied variables catalog magnitud is from Sky2000.
