Description:
The Table2 summarizes the photographic magnitudes obtained over 24
years at the Skalnate Pleso (1979-1993) and Asiago (1969-1988)
observatories for 17 variable stars of different types: Miras (7),
Semi-regular (4), Cepheids (3), RR Lyr (2), Eclipsing binary (1).
The cross-reference between star No., designation according to Margoni
and Stagni (1984A&AS...56...87M 1984A&AS...56...87M) and catalogue one (provided it has
already been adopted for a given star) according to the GCVS (See Cat.
II/214) and IBVS (Kholopov al., 1987, See Cat. II/195) is given in
Table3 as well as the equatorial coordinates for the epoch 1950.0 for
each star, which is compatible with the GCVS. In this table are shown
the basic characteristics of the observational material for each star:
the number of data points and interval of magnitudes obtained at the
Asiago Observatory (A) and Skalnate Pleso Observatory (SP) respectively.
