A. The SITe2K CCD is available for direct imaging on the du Pont 2.5-meter telescope, and gives a scale of 0.259″ per pixel over a field of 8.85 arcmin square.
B. The wide field reimaging CCD (WFCCD) camera reimages a 25 arc-minute diameter field onto the WF4K CCD camera, with a scale of 0.484 arcsec/pixel. It produces images of approximately two pixels over the full field, and has good transmission from 3800 Å to 9000 Å. Metal slit masks are used to provide a multi-object spectroscopy capability. Observers should consult J. Mulchaey (firstname.lastname@example.org) or I. Thompson (email@example.com) about mask making procedures and should allow three months for the production of the masks.
C. The B & C spectrograph uses a Marconi CCD mated to a Bowen Schmidt camera as the detector. When used with the 600 line/mm grating the dispersion is 1.5 Å/pixel with a wavelength coverage of 3100 Å. The spatial scale on the du Pont Telescope is 0.70 arcsec/pixel, and the maximum slit length 271 arcsec.
D. The Echelle Spectrograph provides simultaneous wavelength coverage from ~3700-7000 Å at a typical resolution of ~40,000.
E. CAPSCam is a specialized astrometric camera designed for an astrometric search for Jupiter-like planets. The camera employs a Rockwell Hawaii-2RG HyViSI array, and the design is optimized for high accuracy astrometry of red dwarf stars. Observers interested in using this instrument should contact Alan Boss (Carnegie-DTM) or Ian Thompson (OCIW).
F. RetroCam is a near-IR imager built especially for the Carnegie Supernova Program, but which is generally available to users. RetroCam employs a Rockwell Hawaii-1 HgCdTe 1024×1024 array. The focal plane scale is 0.201 arcsec/pixel, with a total field size of 3.4arcmin square. A single filter wheel containing Y, J, and H filters is available.
