Watersled experiment
2 mM C13, N15-Ubiquitin in 5 mM Shigemi tube @ 25C
50 mM KPi, 0.02% NaN3, 50 uM DSS pH 5.8
500 MHz ; sw= 7000, np= 16384, pw=5.3, nt=192
water suppression elements on, tof=-177.3
prepulse of gradients = 'n', gain=24, 
diffusion time = 110 msec, led= 10 msec
gzlvl1 range = 2000 -> 32400 G/cm. 
Last 3 Fids (37,38,39) appeared to operate at 
gzlvl1=2000 not the expected arrayed value.
