spec_par

spec.par

This field contains the fields ‘spec.par.dX’ for each dimension, which then contain relevant acquisition and processing information,. They are optionally provided in the ‘spec.par’ parameter or in the ‘par’ parameter for the FitSpec function. This information may be omitted, in which case the program will default to fitting with pure Gaussian lineshapes (or Lorentzian if specified), but better performance is expected if the information is provided.
