Notes. Here, we present the number and name of the asteroids, observation date and time at the beginning of the acquisition, exposure time, visual magnitude (mv), phase angle (α), airmass at the middle of the exposure time, solar-analog star used for reduction (see Sect. 3.3) with the associated airmass, instrument and slit used. B–C stands for Boller and Chivens spectrograph.
