Notes. The table includes a list of epochs, number of available spectra, the B−V, the visual magnitude, and the mean signal-to-noise ratios (S/N) (in the Ca II H&K region (3880−4020 Å)). The B−V values and visual magnitudes are taken from ESA (1997), except for the Sun. The solar B−V-value is taken from Cox (2000).
