Comparison of GaussPy (left frames) and SPIF (right frames) fits of the C180 spectra of the MHD model. The map resolution is R = 16 and the view direction x. The upper frames show the number of Gaussian components selected by the programs, with the fraction of spectra fitted with one to four components listed within the frames. The lower frames show the corresponding ${\chi }_{\text{N}}^2$ values.
