Notes. The columns report the labels of the time series, the starting times of each series from T0 = 13 April 1999 2:11:34 UT, the exposures, the average rates, and the parameters derived from our analysis.

(*)

This parameter is related to the Fourier power spectrum of the series: S only one peak is present, T two peaks are detected.
