Table 3.

Comparison of frequency groups created from synthetic (random) light curves and the original light curves.

	Synthetic		Original
	P ≥ 0.10	P ≥ 0.15	P ≥ 0.10	P ≥ 0.15

N° groups ^(a)	70	14	160	80
N° f^(b)	596	112	2019	959
$\bar{f}$ $\overline{f}$ ^(c)	83	82.4	68.4	66.1
Mean duration ^(d)	1.7	1.5	2.8	2.6
$\bar{N_{c}}$ $\overline{N_{\mathrm{c}}}$ ^(e)	5.9	5.2	7.0	6.5

Notes. For all the parameters related to random data, the shuffling process was repeated 100 times and the average was calculated.

^(a)

Number of groups found.

^(b)

Number of frequencies forming the groups.

^(c)

Mean frequency (d⁻¹).

^(d)

Mean duration (hours).

^(e)

Mean number of cycles.
