DiskFit: a code to fit simple non-axisymmetric galaxy models either to photometric images or to kinematic maps

arXiv:1509.07120

Abstract

This posting announces public availability of version 1.2 of the DiskFit software package developed by the authors, which may be used to fit simple non-axisymmetric models either to images or to velocity fields of disk galaxies. Here we give an outline of the capability of the code and provide the link to downloading executables, the source code, and a comprehensive on-line manual. We argue that in important respects the code is superior to rotcur for fitting kinematic maps and to galfit for fitting multi-component models to photometric images.

3 pages, the package is available at http://www.physics.rutgers.edu/~spekkens/diskfit/
