Notes. The table columns are as follows, from left to right: the notation, name, observation date in reduced heliocentric Julian dates (RHJD = HJD – 2 400 000), Gaia DR2 G-band absolute magnitude (MG), Gbp–Grp colour, exposure time, and the signal-to-noise ratio per pixel (S/NHe 10 830) at the continuum level around He 10 830 of our sample stars.
