The successive columns of tables contain (based on GCVS):
- The GCVS star number:
- The name of a star in constellation order and link to the diagram
- RA and Dec
- Type of variability
- Magnitude in V
- GCVS Period in days
- Spectral type
Diagrams are presented on individual sub-pages and
computed for an average ephemerides presented in left-bottom corners of pictures.
For small number of data ephemerides for diagram is taken from literature.
Based of last tred on O-C daigrams, an linear ephemerides and current orbital phase is calculated based on YOUR COMPUTER TIME !!!! (If there is enough data after 1960)
The database is described in the paper: "Up-to-date Linear Elements of Close Binaries", J.M. Kreiner, 2004, Acta Astronomica, vol. 54, pp 207-210. Please include a citation when using the database for your research. This project was partly supported by KBN grant No 2 P03D 006 22.
