11001. Презентация PowerPoint

Prague, August 16, 2006 . Our trial revision of the GCVS data for several southern constellations show that type changes are not needed for most stars. ... We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). ... Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS. ...

Prague, August 16, 2006 . Another problem that was making it difficult to automatically merge GCVS and survey catalogs has been recently solved: ?old? variable stars also had only very rough coordinates. The GCVS has been identified, on a star-by-star basis, with positional catalogs. ... The total number of stars we were unable to identify, at least tentatively, is only 200, most of them from two or three sources of especially unreliable positional information. ...
