The MFIT portion of WINGSPAN does forward-folding spectral fitting using a detector response matrix (DRM). Since it is implemented in FORTRAN, its ``look and feel'' is slightly different from the rest of WINGSPAN. MFIT is reached by selecting one of the Fit... commands described above. WINGSPAN will automatically read in the DRM the first time a fit is requested.
Upon the first selection of any menu item, WINGSPAN will ask a series of
standard questions to setup for fitting and displaying plots of the fit
results. Usually you will want the defaults, which can be obtained by entering
return (Carriage Return).
