The GMT-CfA, Carnagie, Catolica, Chicago Large Earth Finder (G-CLEF)


G-CLEF

  • A fiber fed, optical echelle spectrograph

  • Precision radial velocity capability (PRV): dV<10cm/sec

  • Observation mode : High- Throughput (HT), Precision- Abundance (PA), and Precision Radial Velocity (PRV)

  • Respective resolving powers : R~25,000, 40,000 and 120,000

  • R~40,000 multi-object spectroscopy mode with a multiplex of ~40 fibers

    * Collaboration : Smithsonian Astrophysical Observatory, Pontificia Universidad Catolica de Chile,

    University of Chicago, Harvard University, Observatories of the Carnegie Institute

    of Washington
