keyword=spot_3 for dilution runs, best beam position for current tuningJust to confirm that shifted by 2mm and using 2cm rasters is the best!
A quick test to remove all doubts!!!
Figure 1:
Top left: empty target, 2mm shifted, 2cm rasters
Top right: C12, 3mm shifted 2cm rasters
bottom left: C12, 3mm shifted, 1.9cm rasters
bottom right: C12, 2mm shifted, 2.0cm rasters 41188
Seem like the run 41188 still hitting the cup for carbon, but it will
not hit the cup of NH3 since the inner diameter of the latter is 1mm larger. This is proved by Figure 2, which is for dummy target. One can tell the NMR coil except color blind.
