The following tasks belong to the category ROTATION-CURVES:

- 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.
*See also:*INSPECTOR Supplementary documentation. (inspector.src) - 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. (velfi.c)
