The following tasks belong to the category MODELS:

- FINDGAUSS
- Fitting and subtraction of 2-D gaussians (findgauss.c)

- Apply a flat field correction to a map by fitting a 2-D polynomial to the background. (flat.c)
- GALMOD
- Making model observations of the HI gas in a spiral galaxy. (galmod.f)
- gaufit2d
- Find position or major-, minor axis and position angle of sources by fitting 2 dim. gauss function parameters to data in a box.. (gaufit2d.c)
- GAUSSCUBE
- Making the full datacube of the results of a gaussfit. (gausscube.f)
- QFIT
- Interactive fit of 2-D gaussians (qfit.c)
- RECTIFY
- Review the geometrical component of a model galaxy by fitting surface densities in (user supplied) tilted rings. (rectify.c)
- ROTMAS
- Interactive modeling of rotation curves (rotmas.c)
- ROTMOD
- This program calculates the rotation curve for a truncated exponential disk (Casertano, M.N.R.A.S., vol. 203, p735-p747, 1983), or for any other user supplied density law. It can also calculate the rotation curve for a spherical bulge. (rotmod.c)
- VELFI
- Calculates model velocity field from input parameters given by the user. (velfi.c)
