velfit: A Code for Modeling Non-Circular Flows in Disk Galaxies

[c]velfit: A Code for Modeling Non-Circular Flows in Disk Galaxies[/c][/b]
Abstract: High-quality velocity maps of galaxies frequently exhibit signatures of non-circular streaming motions. velfit yields results that are more easily interpreted than the commonly used procedure. It can estimate the magnitudes of forced non-circular motions over a broad range of bar strengths from a strongly barred galaxy, through cases of mild bar-like distortions to placing bounds on the shapes of halos in galaxies having extended rotation curves.

This code is no longer maintained and has been superseded by DiskFit (ascl:1209.011).

A frontend to velfit is available as runvelfits07 in the NEMO package. See also http://www.astro.umd.edu/nemo/man_html/ ... s07.1.html

velfit has been superseded by diskfit (ascl:1209.011), which has the velfit method as one of its options.
