Description:
We present a library of 952 synthetic spectra characterized by
-2.5≤[Z/Zsun]≤+0.5, 4.5≤logg≤1.0, 3500≤T(eff)≤50000K, at a
resolving power (lambda/Delta_lambda) of 20000 over the wavelength
range 7650-8750Å. The wavelength range covers the near-IR Ca II
triplet and the head of the hydrogen's Paschen series, the K I doublet
(7664, 7699Å), the Na I doublet (8183, 8194Å) and the lines of
Fe I multiplet N.60 at 8327 and 8388Å. The synthetic spectra are
based on Kurucz's codes and line data.
