The PROFIT is an IDL routine to do automated fitting of emission-line profiles by Gaussian curves
or Gauss-Hermite series otimized for use in Integral Field and Fabry-Perot data cubes. As
output PROFIT gives two-dimensional fits files for the emission-line flux distribution, centroid velocity,
velocity dispersion and higher order Gauss-Hermite moments (h3 and h4).

To run PROFIT the following routines are required:
If you used the PROFIT routine I would appreciate if you cite the following paper: Riffel (2010, Ap&SS, 327, 239)
