    IFSFIT is a general-purpose library for fitting the continuum,
    emission lines, and absorption lines in integral field spectra
    (IFS):

    https://github.com/drupke/ifsfit

    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
    velocity components.

    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,
    and WiFeS.

    Please reply to this post or drop me an e-mail (gmail: drupke) if you find that this software works well for you, or if you find problems with it.
