Observational conditions: for each object we report the observational date and universal time (UT of the beginning of the exposure), the geocentric distance ($\Delta$), the heliocentric distance (r), the phase angle ($\alpha$), the total exposure time, the airmass (mean of the airmass value at the beginning and at the end of observation), the observed solar analogue stars with their airmass used to remove the solar contribution, and the spectral slope value computed in the 0.5-0.8 $\mu$m range. The TNOs and Centaurs observed in spectroscopy for the first time are in bold.
