Fig. 4 in the paper shows RMSE labeled in Hz:

but the data passed to compute_rmsd is all "w" arrays like wtrue in units of rad/s
https://github.com/ClaireYLin/regularized-field-map-estimation/blob/1e60f83feb7baafd5d767e777f8fd68033488ea3/examples/example_simu_fieldmap.m#L122
So perhaps the actual RMSE values are 2\pi lower than what is shown in Fig. 4, right?
Please just reply without changing code because I am in the middle of making several changes.
