Zusammenfassung: | We present NSV Release 2, an electronic version of the “New Catalogue of Suspected Variable Stars”. A detailed file-by-file description of the new catalogue version is given. By its structure, we preserve the catalogue as a historical document, but the information it contains has been considerably renewed compared to its first electronic version. Accuracy of coordinates has been drastically improved for the objects in the catalogue; for most of them, we revised photometric and spectroscopic data. Remarks have been renewed. In the cases when there were no finding charts, we recovered variability of 2800 stars of the catalogue, despite large errors of the coordinates earlier published for them. Using photometric data from several sky surveys, we studied and transferred to the General Catalogue of Variable Stars about 5000 NSV stars. |
