//                with a Z-filter consistening of a short mix period, aHmix = 0.0.

//              Argument 1 is the action: 'setup', 'process' or 'plot'. The
//              action 'setup' initiates an experiment.  The actions 'process'
//              and 'plot' are called by chempackQ.

//              Argument 2 is the nucleus, 'C13' (only). The second nucleus is
//              assumed to be 'N15'.

//              Argument 3 is the '13C' region, 'alpha' (alpha carbons) or 'carbonyl'
//              carbonyl carbons. The second region is assumed to be 'amide'. The
//              region-code is 'NCa' for 'alpha' and 'NCO' for 'carbonyl'.
