The IRTF Spectral Library is a collection of 0.8-5.0 um mostly stellar spectra observed at a resolving power of R ~ 2000 with the medium-resolution spectrograph, SpeX, at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea.
The IRTF Extended Spectral Library is a collection of 0.7-2.5 um mostly stellar spectra observed at a resolving power of R ~ 2000 with the medium-resolution spectrograph, SpeX, at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea. It expands the metallicity coverage of the original IRTF Spectral Library (Rayner et al. 2009) from mainly solar metallicity to -1.7 < [Fe/H] < 0.3.
