  Note: The 20µ atmosphere at Palomar, particularly during the summer, often resembles a brick; proposals should concentrate on 7µ-14µ work and consider anything at 20µ a fringe benefit.

Sensitivity:

• 150-200 mJy @ N (1 in 1 second on point source in a 1.5 arcsec square false aperture)

Instrument Control:

• Sun SPARCstation (UNIX/OpenWindows)
• Rackmount 486 (Linux)
• FITS output to disk/exabyte
• Custom control and user interface programs
• Simple data reduction with user interface
