Notes.  is the mean magnitude in V filter, the V absolute magnitude assuming the distance modulus m − M = 18.49 ± 0.05 mag (Pietrzyński et al. 2013) and AV = 0.25 mag (Paunzen et al. 2011), the mean colour index, Δa the mean Maitzen index, NV and NI the numbers of V and I observations, δmV and δmI the typical uncertainties of particular measurements, 1/P the frequency of the maximum effective amplitude of Am or S/N, while Am and Ams are the observed maximum modified amplitude and expected maximum modified amplitude. S/N and S/Ns are the maximum signal/noise value and its expected value; “prob” means the probability of the reality of designate frequency of periodic variations. Bold numbers designate higher values than the particular mean values.
