 +==== Amplitude Calibration ====
 +
 +Tsys measurements from LBA telescopes are frequently missing or subject to significant errors, especially at frequencies where RFI is an issue. This is a significant complication for data analysis especially where accurate flux deck densities are required. It is strongly recommended to regularly observe a compact calibrator that is part of the ATCA calibrator monitoring program to provide amplitude calibration bootstrapping. Such a source should preferably be within approx 10 degrees of your target sources. Your phase calibrator will often be suitable.

 +It is also possible to use the ATCA local interferometry data to provide this calibration for a source that is not in the monitoring program. Please consult with observatory staff before committing to this strategy.
