TL;DR: In this paper, new measurements were used to determine the brightness temperatures of Venus, Jupiter, Uranus, and Neptune at 750 μm and of Venus and Jupiter at 450 μm using Mars as the primary calibration standard.

TL;DR: In this paper, the flux from the central region of the Crab Nebula in three broad spectral passbounds with flux-weighted mean wavelengths of 300 microns, 400 microns and 1 mm has been measured.
Abstract: The flux from the central region of the Crab Nebula in three broad spectral passbounds with flux-weighted mean wavelengths of 300 microns, 400 microns and 1 mm has been measured. The inferred total flux densities for the entire nebula are consistent with an extrapolation of the power law spectrum found at longer wavelengths. Derivations of various flux densities are presented, and it is concluded that the luminosity of dust emission from the Crab Nebula varies between 1300 and 5000 suns as the temperature varies from 40 to 120 K, respectively.
