Table 1
Fractions of stars more variable than once and twice the solar level, and fractions of periodic stars in the high and low variability groups (see Sect. 4.1 for definition).

Notes. The random uncertainty for each of the measurements is < 0.5%, and is negligible in comparison to difference introduced by the choice of dividing line, demonstrated by the 1 and 2 times the solar value comparisons listed in this table (see Sect. 3.2 for further discussion).
