-
- INSPECTOR writes slices through a 3d GIPSY data cube.
It overlays radial HI velocities (i.e. 'tilted ring'
circular velocities) on velocities in XV diagrams and
lets you adjust the tilted ring parameters to get a
better fit.

- reswri
- RESWRI derives the kinematical parameters from the observed
velocity field by fitting tilted-rings to the velocity field
and fits harmonic terms after convergence of the ROTCUR part of
code. RESWRI uses the 1 sigma error-field to calculate its
errors.
(reswri.c)
- ROTCUR
- ROTCUR derives the kinematical parameters from the observed
velocity field by fitting tilted-rings to the velocity field.
(rotcur.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.
