- for the cold probe, N15 decoupling power level should be low (e.g. dpwr2=41 or less), and “at” should be short.
- make sure shpw1=8*pw if href_flg=’y’
- “dof” should be set to the center of “CO”.
- array d1 from 0.3s to 0.45s, and find a good value for the better signal and the proper collecting time.
