Evidence that TABASCAL achieves phase calibration off the strong RFI sources: A comparison of the root mean squared error (RMSE) in gain phase estimates and the posterior standard deviations from TABASCAL. TABASCAL shows statistically rigorous phase calibration capabilities that depend on the RFI S/N. Above an S/N of 1. phase constraints are inversely proportional to the RFI S/N. Below an S/N of 1, phase solutions are found within the prior information given.
