加州大学哈特克里克天文台的三天线毫米波长阵列和85英尺望远镜将进行一项研究计划。85英尺的望远镜将继续参与超长基线（VLBI）网络的厘米波长，并将继续对银河系进行大规模光谱调查。毫米波长阵列将在2.5至4.0毫米波长范围内进行连续光谱和谱线测绘。工作人员和参观者将讨论各种各样的问题，重点是恒星的形成和恒星演化的后期阶段。还将研究太阳系、星际介质、超新星遗迹、正常星系和活动星系、射电星系和准恒星天体（QSO）中分子气体和尘埃的分布以及2.7 k宇宙微波背景辐射。将开发1.3毫米波长观测接收器，然后用于对目前的3毫米波长研究进行观测补充。

A program of research with the three-antenna millimeter-wavelength array and the 85-foot telescope at the Hat Creek Observatory of the University of California will be carried out. The 85-foot telescope will continue its participation in the Very Long Baseline (VLBI) Network at centimeter wavelengths and will continue in its large-scale spectroscopic surveys of the galaxy. The millimeter-wavelength array will pursue continuum and spectral line mapping at 2.5 to 4.0-millimeter wavelengths. A wide class of problems will be attacked by both staff and visitors, with a strong emphasis on star formation and the late stages of stellar evolution. There will also be studies of the solar system, the interstellar medium, supernova remnants, the distribution of molecular gas and dust in both normal and active galaxies, radio galaxies and quasi-stellar objects (QSO's) and the 2.7-k cosmic microwave background radiation. Receivers for 1.3-millimeter- wavelength observations will be developed and then used to make observations complementary to the current 3-millimeter wavelength studies.
