12 Meter Receiver Tsys Measurements
Below are links to the actual files recorded at the telescope each time a calibration is taken. This files contain most information an observer needs to gauge the performance of the receiver.
Be advised the the Tsys for any one channel may vary due to many factors such as tau0, telescope elevation and the sky frequency being too close to a water line. It is also possible the receiver is being tuned too close to the edge of a receiver band and that too can result in higher then normal Tsys.
These tables are presented for comparison purposes only. You mileage may vary...
