Tsys vs. phase. P. Lilie indicates that second receiver will be installed very shortly. Calibrators need to be sorted out. F. Owen suggests getting their calibrator lists from OVRO and Hat Creek.
Absolute calibration is a serious problem.
A model of 3C 286 could be tried, but with no guarantee of success. Survey F. Owen notes that three antennas out of the array very significantly degrades the observations. This should be avoided as much as possible, and when it cannot be, we may have to reobserve. Interference seems not to be much of a problem except when they are flying balloons from Fort Sumner. These balloons have a downlink at about 1435 MHz.
