CHIRON is a highly stable cross-dispersed echelle spectrometer at the SMARTS 1.5m telescope. It is fed by fiber and intended primarily for precise radial velocities.
- Spectral resolution R~80000 (with image slicer), 3-pixel sampling
- Spectral range 410-870 nm, fixed
- Total efficiency ~6%
CHIRON is operational since 2011B. After recent upgrade, it is back in service since March 2012.
CHIRON replaces the previous spectrometer at 1.5m, FIBER ECHELLE
