Scanpi is an interactive software tool for viewing, plotting, and averaging the calibrated survey scans from the Infrared Astronomical Satellite (IRAS). The 1-dimensional scans are the fundamental data from the IRAS survey. Scanpi is useful for measuring the fluxes of extended, confused or faint sources, for diagnosing source extent, and for estimating upper limits. The sensitivity gain is about a factor of 2-5 over the IRAS Point Source Catalog (PSC), depending on the local noise and number of scans crossing the target position. Scanpi allows users to interactively group, plot, and coadd IRAS scan data at any sky position. Tables can also be uploaded. Scanpi is intended for immediate access to the basic IRAS data for users wishing to process their positions interactively.
