Global Calibration<br />
We are also able to calibrate multiple subbands simultaneously.<br />
Again, just a few lines needed in the parset file..<br />
For example, 10 subbands of our Cygnus A observation:<br />
>Strategy.UseSolver = T<br />
>Step..Solve.CalibrationGroups = [10]<br />
No more than 5-10 subbands (1-2MHz bandwidth) should be used due to<br />
increasing problems with ionosphere & station clock drift.<br />
Global calibration is particularly helpful for fainter fields, where S/N from just one<br />
subband is low.<br />
