\caption{\label{obs-cir}Observational parameters. For each asteroid we give its denomination, the night of observation, the UT start time, the exposure time, the airmass, the apparent visual magnitude, the solar phase angle, $\alpha$, the solar analog star used in the reduction and an observatory code where E, C and O indicate ESO, CASLEO and OPD, respectively. In the last column {\it s/n} indicates, for each asteroid, the number of obtained spectra, $s$, distributed on how many different nights, $n$.  The values for the night of observation, start and exposure time, apparent visual magnitude and phase angle refer to just one selected spectrum.  This spectrum was chosen as the one with the smallest noise between 0.65 and 0.70 $\mu$m since in this region all spectra are quite linear and with no strong features regardless of their taxonomic classification.}
