A high-resolution K-band spectral atlas of massive stars

This dataset contains reduced, telluric-corrected K-band spectra of 81 early-type stars described in the Astronomical Journal article 'A high-resolution K-band spectral atlas of massive stars' taken using the IGRINS spectrograph when mounted on the Gemini South telescope. The data are available as order-merged and normalized spectra in ascii format. The raw and reduced data (without the additional telluric corrections performed by the xtellcor software) are also available publicly via the Gemini archive. For further queries or requests, please contact the authors. Note that the spectrum of NGC 3603 A3 is contaminated from the cluster centre (incl. A2, A1 and B) and is only provided as a reference.
