Note (2): 1 = Highest-quality sample, obtained with FAP levels set by a correlation timescale of 1 day (as in R01); 2 = Likely periods, obtained via a correlation timescale of 0.5 days or added manually based on the quality of the light curve. Note (3): e = These stars fall in the regions defined in Table 2. Stars 164, 2537, and 3051 have a high enough normalized power to be considered periodic even with the higher 1% FAP limit set with the 1 day correlation timescale; see text. Note (4): 1 = True; these stars were used in Rebull et al. 2002b. Note (5): 1 = True; these stars were used in Rebull et al. 2004. --------------------------------------------------------------------------------
