;pl1 : f1 channel - power level for pulse (default)
;pl9 : f1 channel - power level for presaturation
;p1 : f1 channel -  90 degree high power pulse
;p2 : f1 channel - 180 degree high power pulse
;d1 : relaxation delay; 1-5 * T1
;d11: delay for disk I/O                             [30 msec]
;d12: delay for power switching                      [20 usec]
;d20: fixed echo time to allow elimination of J-mod. effects 
;        d20 should be << 1/J ,but > (50 * P2)       [1-2 msec]
