Millimeter-wavelength continuum calibration sources

Abstract

High-precision observations of 18 radio sources have been made at wavelengths of 9.55, 3.33, and 2.00 mm between 1971 and 1980. The sources include the Sun, Moon, planets, planetary satellites, asteroids, H II regions, planetary nebulae and a quasar. Analyses of these ddata probide accurate flux densities for the interpretation of source spectra and for the calibration of other radio astronomical observations. A brief description of the observational techniques is gibe, and tables of absolute flux densities are presented.
