Select the line profile for fits. Five type of profiles are available. Up to 5 Gaussian, dependent or independent can be fitted in a spectrum, according to command lines.
Profiles are symmetric.
Up to 5 dependent or independent lines may be fitted. Area units are K.MHz. Compute ammonia line profiles, with the assumptions of gaussian velocity distribution and equal excitation temperatures. This is very similar to the NH3 method, but the coefficient to describe the hyperfine structure are read in the file FileName. The other lines must contain, for each component, the velocity offset and the relative intensity.
