It uses PPXF (the Penalized Pixel-Fitting method developed by
Cappellari & Emsellem, 2004, PASP, 116, 138) to find the best fit
stellar continuum (using a user-defined library of stellar templates
and including additive polynomials), or optionally a user-defined
method to find the best fit continuum. It uses MPFIT to simultaneously
fit Gaussians to any number of emission lines and emission line
Included in this version is a procedure that is optimized
for the GMOS instrument (init/IFSF_GMOS.pro) and contains line
parameters pertaining to strong emission lines in the wavelength range
4000-7000 A. However, this code can be relatively easily adapated to
other instruments and to include parameters (like fixed line ratios)
for other emission lines. The code has in the past been used to
successfully fit data from many instruments: GMOS, LRIS, NIFS, OSIRIS,
