Welcome to the Raw & Reduced IGRINS Spectral Archive!

Version 3: Hosting data taken between July 2014 and May 2023

IGRINS is a high resolution (R ~ 45,000) spectrograph that simultaneously covers H- and K-band (1.45-2.45 μm) in a single exposure built as a collaboration between the University of Texas at Austin and the Korean Astronomy and Space-Science Institute. Since coming online in the summer of 2014, IGRINS has spent over 1,000 nights on sky collecting spectra on 3,400 unique targets. RRISA allows anyone to access raw and reduced IGRINS archival data!
