[ascl:1010.021] velfit: A Code for Modeling Non-Circular Flows in Disk Galaxies
Spekkens, K. J.; Sellwood, J. A.
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This code is no longer maintained and has been superseded by DiskFit (ascl:1209.011).
