General Catalogue of Variable Stars

C2A natively includes the GCVS catalogue (General Catalogue of Variable Stars). This catalogue is provided with the standard distribution of C2A and does not need to be downloaded separately. The current version of this catalogue includes 45,679 objects. This includes the digital version of the GCVS4 catalogue Vols. I-III (Kholopov et al. 1985-1988) and the "Name-Lists of Variable Stars" Nos.67-78 published during the preparation of the 4th edition of the GCVS catalogue.

You select the GCVS catalogue as the current catalogue through the Stars tab of the Options dialogue box, or by SHIFT-right-clicking on the map. The variable stars are represented on the maps by conventional symbols (two nested discs for variable stars).

All the required information on the GCVS catalogue is available on: http://www.sai.msu.su/groups/cluster/gcvs/gcvs/
