本文报道了太阳、新月、金星、火星、木星、土星和天王星的亮温和DR 21在2.1毫米波长处的流量密度的绝对测量结果。在3.5毫米波长的相对测量也解决了德克萨斯大学16英尺射电望远镜和航空航天公司15英尺天线之间的绝对校准差异。根据最近的观测结果,讨论了使用明亮的行星和DR 21作为毫米波长的绝对校准源。
Absolute measurements of the brightness temperatures of the Sun, new Moon, Venus, Mars, Jupiter, Saturn, and Uranus, and of the flux density of DR21 at 2.1-mm wavelength are reported. Relative measurements at 3.5-mm wavelength are also presented which resolve the absolute calibration discrepancy between The University of Texas 16-ft radio telescope and the Aerospace Corporation 15-ft antenna. The use of the bright planets and DR21 as absolute calibration sources at millimeter wavelengths is discussed in the light of recent observations.
