ABSTRACT

We describe the process by which single dish aperture efficiency measurements
are carried out for the antennas of the CARMA array. The basis for the
measurements is explained and the practical details are described. Related
topics such as the approximations used at CARMA to calculate atmospheric
opacity from weather data, the analysis of sky dips to actually measure
atmospheric opacity, the model for lunar brightness temperature and
effective primary beam sizes are also discussed.
