Notes. The periods are sorted by L-S power of the combined data in a descending order. It should be noted that the 263.35 d period is the fifth most significant period in the Lick data but was put in last place for comparison with the 264.69 d in the combined data sets. The significance threshold is a FAP of 0.1%.
