Description
In this paper we complete the library of synthetic spectra for the range 7650-8750{AA}, which includes the 8500-8750{AA} interval currently base-lined for the spectroscopic observations by GAIA, candidate ESA Cornerstone 5 mission. As for Paper II (Munari & Castelli, Cat. <J/A+AS/141/141>), the spectra are based on Kurucz's codes and line data. The explored metallicity, gravity and temperature ranges are -2.5<=[Z/Z_{sun}_]<=+0.5, 4.5<=logg<=2.0 and 7750<=T_eff_<=50000K, respectively. The 698 new spectra are computed at the same {lambda}/{Delta}{lambda}=20000 resolving power of the observed spectra given in Paper I (Munari & Castelli, Cat. <J/A+AS/137/521>) (131 standard stars mapping the MKK spectral classification system) and the 254 synthetic spectra of Paper II (characterized by T_eff_<=7500K).
