Near-IR spectra of the 10 TESIS ETGs
The near-IR spectra of the 10 ETGs collected within the TESIS survey have been obatined with the Amici prism at the near-IR camera and spectrograph NICS at TNG the italian 3.5m telescope. The spectra are characterized by a resolution R~50 and cover the range 0.9-2.3 mu.
The observations, the instrument setup and the data reduction are described in Saracco et al. 2003, 2005 and in Longhetti et al. 2005.
The available spectra are in units of
10-18 erg cm-2 s-1 Å-1.
