A second test run is scheduled for late August and, weather permitting, more information on sensitivity will be posted on the Web site in early September. Availability Phoenix will be available on the 2.1-m telescope starting in January 1997. Time in January is available on a shared risk basis by submitting a proposal with January specified. Shared risk proposals will be accepted up to the normal spring semester deadline of 30 September. Phoenix will be available as a facility instrument on the 2.1-m telescope starting in February.
Phoenix has an internal dichroic allowing the simultaneous detection of visible and infrared light.
One may then acquire an object through the 1' diameter open aperture, move to the desired slit, and center up by imaging the object through the slit. Any object in the visible channel field may then be used for telescope guiding. Tests show that flexure between the visual and infrared images is not measurable at the one pixel level.
