For CAS-14723, add VisCal::currFreqHz() to support use of channel frequencies in Hz (same as MS units) in calibration calculations like phase(delay), etc.
Pull request #1052: CAS-14694
Merge in CASA/casa6 from CAS-14694 to master
* commit '6f1345ac52f7252da24ccdc916163333039734d1':
For CAS-14694: In SolvableVisCal::setSimulate, for simulation of DJones only, short-circuit VI major and minor iteration over the MS so that instrumental polarization is neither time- nor (for mosaic sims) field-dependent. This breaks 'testSky_intLeak' in test_task_simobserve.py. NB: this is not yet a complete polarimetry simulation because parang is not yet treated. CAS-14694: update simobserve task built-in help for leakage parameter CAS-14694: make simobserve produce full-pol simulation when input model image is full-pol, independent of leakage CAS-14694: activated test case testNZ_intMan_Leak and made sure leakage is only applied for obsmode='int'
Enable teardown for test_task_simobserve CAS-14694: Made ANoise::nPar() in AMueller.h return 4 instead of 2. CAS-14694: changes which seem to solve the remaining problems CAS-14694: reverted use of sm.setfeed in simobserve task CAS-14694 modified the task script to make appropriate sm tool calls when leakage>0
