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.
