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 "---".
