General Catalogue of Variable Stars V1.1, Vol. IV

We tried to provide as complete lists as possible for the stars identified with the catalogues HD, BD, CoD, CPD, BS, ADS and for the stars with preliminary HV (Harvard Variable) designations. As for the other catalogues, our task here was more difficult since we had to rely upon references to source catalogue names made by variable star researchers; the tables in the present volume reproduce the materials used in our work, and incompleteness seems to be inavoidable.

The differences between the computer-readable version 1.0 [1] and 1.1 of vol. IV are the following : 1. Stars of the 71th and 72th name-lists of variable stars [2,3] have been added. 2.

For extragalactic variable stars, we present identifications between source catalogues and the GCVS Vol. V [4]. 3. After the publication of the NSV catalogue [5], rather many NSV stars received their final GCVS names (in the system of GCVS Vols.

I-III [6] and subsequent name-lists). A number of stars have two or more different GCVS names. Recently many GCVS stars in the regions of external galaxies got new names in the system of GCVS Vol.

V. The first cross-identification table presents all aliases of presently-accepted official GCVS names. 4. Similarly, the second cross-identification table presents aliases of NSV designations. 5. The cross-identification tables now additionally include the lists of Harvard (HV) and Vatican (VV) variable stars. 6.

All necessary corrections found during 3 years elapsed since the publication of the version 1.0 have been added. 7. We have excluded our very incomplete lists of cross-identifications for X-ray sources (GX, X, XX [1]). Vol.

IV version 1.1 consists of 32 cross-identification tables with the catalogues and lists arranged in the alphabet order of the abbreviated names of source catalogues and lists (see the Note following the file description). They are preceeded with two more tables, those for GCVS and NSV catalogs, playing a role differing from those of the rest of the tables. The first one contains GCVS stars having also NSV catalog names or/and names within corresponding galaxies in the GCVS Vol.

V. The second one contains NSV catalog stars having names within corresponding galaxies in the GCVS Vol. V or/and alternate NSV catalog names (cases of duplicate entries for a single star in the NSV catalog); only stars without GCVS (Vols. I-III) names are included.

The names in the first column of each of these two tables are considered principle names of corresponding stars; these stars enter the rest of the tables ONLY under such first names.
