FITTING tasks
The following tasks belong to the category FITTING:
``Fitting of data''
In parentheses the name of the source file is given.
- 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)
- 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.
