Abstract | The results of continuum measurements at mm and sub-mm wavelengths made with a bolometer in October-November 1982 and February-March 1983 are reported. The campaign was carried out to examine the suitability of the Mt. Lemmon site for construction of a 10 m sub-mm telescope. The survey covered H II regions, warm and cold clouds, spiral galaxies and other objects. Atention was focused on dust properties and linking the radio calibration system with the system used for sub-mm/FIR observations. A summary of the data for the 40 objects observed is provided. Skies free of clouds permitted 1 mm observations. A fast switching mode reduced the sky noise levels to the point that radiometer noise was dominant. Dust color temperatures were 50-60 K for H II regions, 40-50 K for warm clouds and about 20 K for normal spiral galaxies. The cold cloud masses were estimated using flux densities at 1 mm. |
