3. New times of minima

A total of ten primary and ten secondary times of minima were calculated using the well known method of Kwee & Van Woerden (1956) and are listed in Table 4 (click here) with their type of minima and number of observations incorporated in the determination of the times of minima. The average times of minima (together with their standard deviation), obtained from the individual estimates of some cycle, but at different passbands, are given in the last column of Table 4 (click here). By using our last seven times of minima we determined the following light elements:

where the epoch is the improved time of the last of our observed primary minima. Because of the variable period, the new linear elements will be valid only a few years around 1994.
