Notes. Column P is the approximate period of the signal with the largest amplitude in BRITE-Constellation data, and νmax, νlow, and νhigh are the frequency of the maximum oscillation power and the characteristic frequency of the low- and high-frequency component of the granulation signal, respectively. τACF corresponds to the width of the sinc-function fitted to the autocorrelation function of the time series. The indices for log g denote that the value is determined from a seismic or granulation measurement (S/G) or from the ACF time scale (ACF). Stellar radii (R) are listed as determined from measurements found in the literature (sources and methods are given in the notes). Stellar masses are derived directly (Mdirect) and via grid modelling (Mgrid). The last column gives the probability that a star is in the RGB phase of evolution (i.e. not in the RC phase). Based on:
interferometric angular diameter (Richichi et al. 2005) and Gaia DR2 parallax;
