Notes. The 2011 data are short (4 days long) and thus less resolved than the 2012 data (33 days long). The 15.77 c/d is close to two other frequencies, while the 20.79 c/d mode is isolated. Frequencies (F) are in c/d, their uncertainties are in 10−4 c/d, while amplitudes (A) are in ppm as their uncertainties.
