The following tasks belong to the category FITTING:

- ASTROM
- Determine the sky-projection parameters CRVAL, CDELT, CRPIX and CROTA (astrom.c)
- ELLFIT
- Programme fits an ellipse to an user defined bunch of points. (ellfit.c)
- FINDGAUSS
- Fitting and subtraction of 2-D gaussians (findgauss.c)
- FIT
- Fit a set of data points (Xi,Yi) to a model, that depends nonlinearly on its parameters, using a Chi-squared minimization. (fit.c)
- FLAT
- Apply a flat field correction to a map by fitting a 2-D polynomial to the background. (flat.c)
- 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)
- RADIAL
- Derive radial surface density distribution from a 2-dim total HI map using the 'Lucy method'. (radial.c)
- RADPROF
- Solves the radial surface density distribution from a strip integral of the brightness distribution. USE PROGRAM RADIAL AS FRONT END FOR RADPROF. (radprof.shl)
- SMOOTH
- Smooth sets with a gaussian beam (smooth.shl)
- SPLINEFIT
- Fit spline to data in selected subses and interpolate data for other subsets (splinefit.c)
- SURFACEFIT
- Given values Z at positions (X,Y) and optional standard errors for Z from a text file with data in columns, find best fit parameters for a user given model function F(X,Y) (surfacefit.src)
- XGAUFIT
- XGAUFIT estimates parameters for multi component one dimensional gauss functions using data in selected profiles. It can use these estimates to fit the parameters to the data in a least squares fit. Output is send to subsets in a set. (xgaufit.src)
