General Catalog of Variable Stars (GCVS4.2): Extragalactic Variables
Listed in NASA Data Portal
The General Catalog of Variable Stars (GCVS) is the only reference source on all known variable stars.
Description
This database is based on the electronically-readable version as distributed by the Sternberg Astronomical Institute and Institute of Astronomy (Russian Acad. Sci.), Moscow.
It is the catalog of extragalactic variable stars, an updated version of the list contained in the GCVS (4th edition), Volume V. The total number of entries in this database is 10979 variable stars in 35 stellar systems (including the Magellanic Clouds, the Andromeda Galaxy, etc.). These variables include 144 stars now considered to be non-members of the galaxies in whose fields they lie, and 92 more stars that are possible non-members.

The present improved electronic version of the GCVS 4th Edition, Volumes I-V, combined with the Name-Lists of Variable Stars Nos. 67 - 77, is also available from the Sternberg Institute via anonymous ftp to <a href="ftp://ftp.sai.msu.su/pub/groups/cluster/gcvs/gcvs/">ftp://ftp.sai.msu.su/pub/groups/cluster/gcvs/gcvs/</a> and more information is available via the Web at <a href="sai.msu.su/groups/cluster/gcvs/gcvs/">http://www.sai.msu.su/groups/cluster/gcvs/gcvs/</a>.
This online version of the GCVS Vol. V Catalog of Extragalactic Variable Stars was created by the HEASARC in January 2005 based on <a href="cdsarc.cds.unistra.fr/ftp/cats/II/250">CDS Catalog II/250</a>, table evs_cat.dat. The latter was itself based on on an electronically-readable version that was distributed by the Sternberg Astronomical Institute and Institute of Astronomy (Russian Acad.
Sci.), Moscow. This is a service provided by NASA HEASARC .
