O-C DIAGRAMS AND UP-TO-DATE LINEAR
ELEMENTS OF ECLIPSING BINARIES

When using this database please include a citation to: J.M. Kreiner, 2004, Acta Astronomica, vol. 54, pp 207-210.

Diagrams are computed for an average ephemerides presented in left-bottom corner of picture.
For small number of data ephemerides for diagram is taken from literature.
Based of last trend 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).
