CTIO Instruments Available

The following lists common user instruments available on CTIO telescopes. The last column gives volume number of Newsletters containing relevant articles. Many optical instruments show a "generic" CCD, e.g., "Tek 2K." The most recent summary of specific CCD characteristics is in NOAO Newsletter 45; see also 51, 50, and 33. The principal change since last semester is the removal of the ARGUS fiber-fed spectrograph from service. Watch this space for the availability of Hydra II in 1999.
