Full delay, rate and phase calibration is now done by running FRING again. Apply the previous calibration and set DPARM(8)=0 i.e. request rate solutions. The form of CALSOUR here (note the - sign) requests that all sources are fringe-fitted apart from the input. If the calibrator sources are very resolved then a model of the source should be provided to FRING. If a ``combined IF'' solution is required then set APARM(5)=1.
Check the resulting SN table carefully in SNPLT. Spurious solutions may be edited using SNEDT or SNSMO. Apply the solutions with CLCAL, setting INTERPOL='AMBG'.
