time = 22:18:09.411
command = topshim 

FINE SHIMMING

Parameters:

probe = Z114607_0227
solvent = D2O
shim nucleus = 2H
nucleus optimised for = 1H
o1p (from lock) = 4.70 ppm

Results:


1D Shimming:
echo time must be reduced
echo time must be reduced

NOTE: very poor map quality encountered. You may need to use the CONVCOMP option.

Iteration  1: FWHM Before=28.0 Hz, Target= 0.2 Hz, After= 1.7 Hz
Iteration  2: FWHM Before= 1.7 Hz, Target= 0.8 Hz, After= 2.6 Hz
Iteration  3: FWHM Before= 2.6 Hz, Target= 0.2 Hz, After= 0.8 Hz
Iteration  4: FWHM Before= 0.8 Hz, Target= 0.5 Hz, After= 0.7 Hz
Iteration  5: FWHM Before= 0.7 Hz, Target= 0.2 Hz, After= 4.7 Hz
Iteration  6: FWHM Before= 4.7 Hz, Target= 0.2 Hz, After= 0.4 Hz
Iteration  7: FWHM Before= 0.4 Hz, Target= 0.3 Hz, After= 0.6 Hz
Iteration  8: FWHM Before= 0.6 Hz, Target= 0.2 Hz, After= 0.3 Hz
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) = 5.85
