Abstract:
About 1800 O-C diagrams of eclipsing binaries were considered and
up-to-date linear elements were computed.

Note (1): Minima considered in the calculation of the linear elements as
follows:
all = primary and secondary minima were used
pri = only primary minimum was used
sec = only secondary minimum was used
Note (2): Time used for the best fitting of straight line to the O-C
diagrams (this is not an observational time of minimum!).
The value was arbitrarily set close to JD 2452500.
Note (3): If the number of minima used to determine the elements was
smaller than 8, mean errors were not calculated and assigned to "---".
