Description:
The original catalog lists the flare stars discovered by different
astronomical observatories over an area slightly larger than 20 square
degrees in the Pleiades regions centered on Alcyone. Not all the flare
stars are members of this cluster, membership indicators are provided
in the catalog.
The catalog, combining Tables 1 and 2 of the publication, gives the
data for 1531 flares of 519 flare stars.

are found in the literature as "Ton", or "HCG", which are both
ambiguous.

Historical Notes:
The electronic version of the Tonantzintla catalogue of the
Pleiades flare stars was prepared by M.K. Tsvetkov, K.Y. Stavrev,
and K.P. Tsvetkova, at the Department of Astronomy and National
Astronomical Observatory, Bulgarian Academy of Sciences, Sofia,
in June 1987. This standardized documentation has beed added at CDS,
in May 1996.
