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