Joint Topical Meeting on Information Processing in Astronomy and Optics.
During January, 1981, the CT10 4-m telescope was used with a 6-detector bolometer array spectrometer (Gehrz, Hackwell, and Smith, 1976, P.A.S.P., 88, 971) to make maps of Eta Carina simultaneously at wavelengths of 8.1, 8.9, 10.2, 11.3, 12.2 and 13.1

We describe a new design for an astronomical polarimeter optimized for use in the 8 to 13p spectral region based on an earlier visible wavelength instrument. The combination of a special infrared ZnSe birefringence modulator and a background-limited

We have investigated the continuum properties of the superluminal quasar 3C 345 with monitoring studies at radio, optical, infrared, and X-ray frequencies as well as with simultaneous multifrequency spectra extending from the radio through the X-ray
