CHIRON: fiber echelle at CTIO 1.5-m telescope

CHIRON is a highly stable cross-dispersed echelle spectrometer fed by fiber and intended primarily for precise radial velocities. Its major parameters are

  • Spectral resolution R~80000 (with image slicer), 3-pixel sampling
  • Spectral range 410-870 nm, fixed
  • Total efficiency ~5% (preliminary data)

CHIRON is deployed at the 1.5m telescope. It was offered in 2011B. Presently it is in the prpocess of upgrade, to resume operation in March 2012. CHIRON replaces the previous spectrometer at 1.5m, FIBER ECHELLE
