Results:


1D Shimming:
echo time must be reduced
Iteration  1: FWHM Before= 0.2 Hz, Target= 0.6 Hz, After= 3.8 Hz
Iteration  2: FWHM Before= 3.8 Hz, Target= 1.2 Hz, After=35.9 Hz
Iteration  3: FWHM Before=35.9 Hz, Target= 1.3 Hz, After= 0.3 Hz
Iteration  4: FWHM Before= 0.3 Hz, Target= 1.1 Hz, After= 0.2 Hz
Iteration  5: FWHM Before= 0.2 Hz, Target= 1.1 Hz, After= 0.5 Hz
Iteration  6: FWHM Before= 0.5 Hz, Target= 1.0 Hz, After= 1.2 Hz
Iteration  7: FWHM Before= 1.2 Hz, Target= 1.0 Hz, After= 1.5 Hz
Iteration  8: FWHM Before= 1.5 Hz, Target= 1.6 Hz, After= 0.4 Hz
Iteration  9: FWHM Before= 0.4 Hz, Target= 1.1 Hz, After= 0.2 Hz
Iteration 10: FWHM Before= 0.2 Hz, Target= 0.9 Hz, After= 7.4 Hz
Iteration 11: FWHM Before= 7.4 Hz, Target= 0.4 Hz, After=27.2 Hz
Iteration 12: FWHM Before=27.2 Hz, Target= 0.9 Hz, After= 0.5 Hz
Iteration 13: FWHM Before= 0.5 Hz, Target= 1.6 Hz, After= 0.4 Hz
Iteration 14: FWHM Before= 0.4 Hz, Target= 1.0 Hz, After= 0.5 Hz
Iteration 15: FWHM Before= 0.5 Hz, Target= 0.9 Hz, After= 1.1 Hz
RMSD between target and map above threshold but maximum number of iterations reached. Halting shimming.

Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, spinning) = 1.07


Performing tune after shimming
tune lock level increase = 1.2

Fixed offsets were added to compensate for temperature effects: Z = +15, Z2 = +0
