KOA NIRSPEC Data Release

The Keck Observatory Archive (KOA) has released browse-quality spectra extracted with a new, automated pipeline from 1,821 nights of NIRSPEC high-dispersion data. The data products include flux and noise spectra and spatial profiles for each order and wavelength calibration line identification tables in ASCII and FITS formats, a total of over 4,400,000 files altogether; see the sample products below. The pipeline is written in Python, is freely available at and documented at  A quick-look reduction mode is available to observers at the telescope.
