Notes.

^(a)

Upper half: frequencies found in g′ light curve; lower half: frequencies found in i′ light curve;

^(b)

errors as given by FAMIAS, more realistic is an error around 0.1–0.2 mHz;

^(c)

reference time: first point of light curve: g′: BJD_TBD = 2 456 519.5846905; i′: BJD_TBD = 2 456 520.53415896.
