3. The catalogue

Astrometric and photometric results for the 1061 variables are catalogued in a table which is available in electronic form at CDS, and part of which is displayed for illustration as Table 3 (click here) in the printed version of this paper. This table also includes 13 variables belonging to the GCVS, but for which we provide identification charts as well as more accurate positions and Red magnitudes at observed maximum and minimum. The content of the successive columns is as follows:

Column 1: Star number. The numbering starts at 3380 for continuation of a previous list of already published variable stars (Terzan et al. 1982, 1988, 1991). The stars are classified according to increasing right ascension.

Columns 2 and 3: Equatorial coordinates referred to the equinox 2000.0.

Columns 4 and 5: Galactic coordinates tex2html_wrap_inline1578 and tex2html_wrap_inline1580.

Columns 6 and 8: tex2html_wrap_inline1582 and tex2html_wrap_inline1584, the R magnitudes of the star at the observed maximum and minimum brightness.

Columns 7 and 9: E: Identification number of the plate corresponding to the epoch of observation of tex2html_wrap_inline1590 and tex2html_wrap_inline1592 (Table 2 (click here)).

Column 10: A: Observed amplitude, tex2html_wrap_inline1596.

Column 11: Identification of the star in the GCVS catalogue (Kholopov et al. 1985, 1987). For IRxxx stars, see Terzan (1965) and references therein.

Finding charts for all the stars (from R plates) are grouped on plates 1 to 17. North is up and east is to the left, and scales are identical for all charts.
