Near-infrared calibration systems for precise radial-velocity measurements

We present work done to prepare two new near-infrared calibration sources for use on high-precision astrophysical spectrographs. Uranium-neon is an atomic calibration source, commercially available as a hollow-cathode lamp, with over 10 000 known emission lines between 0.85 and 4 ìm. Four gas cells — containing acetylene, H13CN, 12CO, and 13CO, respectively — are available as National Institute of Standards and Technology (nist)Standard Reference Materials (SRMs), and provide narrow absorption lines between 1.5 and 1.65 ìm. These calibration sources may prove useful for wavelength-calibrating the future near-infrared high-precision radialvelocity spectrometers, including the Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph (CARMENES)1 and the Habitable-Zone Planet Finder (HPF).2
