Notes. The different columns report: the name of the star, the heliocentric Julian day on which the spectrum has been collected, the phase, exposure time, S/N per pixel, effective temperature, logarithm of gravity, microturbulent velocity, broadening velocity, heliocentric radial velocity, and the instrument used to collect the HiRes spectroscopy. The phases were calculated adopting periods and epochs of maximum light from the Gaia DR3 catalogue (Ripepi et al. 2023), except for seven stars for which we report details on the phase determination in Appendix B. A portion is shown here for guidance regarding its form and content. The machine-readable version of the full table is published at the CDS.
