If you’re using the fit_svs function in your research please cite [1], [2].

The following methods are used in fit_svs by default:

• rats dynamic frequency and phase correction [3]
• water reference concentration scaling [4]

When separate coil information is available the GLS method of combination is used [5].

The following methods are used in fit_svs depending on the input options:

• Klose method for eddy current correction [6]
• HSVD residual water removal [7]
