The SFI++ data set is a catalog of homogeneously derived photometric and rotational quantities for roughly 5000 field and cluster galaxies in the local universe (cz<20,000 km/s) and their implied Tully-Fisher distances and peculiar velocities. These peculiar velocity measurements can be used both to provide a cosmographic description of the local matter and velocity fields, and to constrain cosmological parameters. In this poster, we describe some of the early results of SFI++, and show the spatial distribution of objects, and the observed velocity field in the vicinity of several features of local large scale structure. This poster represents a precursor to a Wiener Filter reconstruction of the full 3D SFI++ velocity and density fields, to be presented in the near future. The complete SFI++ catalog is publicly available online at http://arecibo.tc.cornell.edu/hiarchive/sfiplusplus.php and we encourage the community to make use of this data set.
