Notes. ID: spectrum identification. Date: listed observing date. UT: observation time when available. Aspect: observing aspect for the nominal pole. α: phase angle.Lat. & Lon.: asteroid-centric coordinates of the sub-observer point. Spec. class: lists the spectral class as determined here, with literature classification in parentheses (some may be based on earlier taxonomies). Wavelength range: type of spectrum with “VIS” for optical and “NIR” for near infrared, “Facility”: code for the instrument used. Ref.: reference to source if the data has been previously published. Facility codes (with MPC codes for the observing site): MDM: MDM observatory McGraw-Hill 2.4-m telescope with Mark III spectrograph (697). IRTF: NASA Infrared Telescope Facility (IRTF) on Mauna Kea with SpeX, US (568). NTTa: ESO NTT telescope with EMMI (809). NTTb: ESO NTT telescope with EFOSC2 (809). PAL: Palomar 200-inch telescope with the Double Spectrograph (675). (a) Unpublished data available at http://smass.mit.edu/data/spex/sp72/, spectral classification provided by Thomas et al. (2014).
