The VAO Spectral Energy Distribution (SED) Tool, Iris

The Virtual Astronomical Observatory (VAO) has just released a beta version of a Spectral Energy Distribution (SED) Tool, called Iris. It is a desktop application that analyzes  1-D astronomical spectral energy distributions (SEDs).

To quote from the release announcement: “Iris is a tool that allows the astronomer to build a SED of a source from multiple, separate data segments or photometric points, gathered from various observatories across a wide spectral range, and fit the aggregate SED with emission and/or absorption spectral models; individual data segments may also be separately analyzed.  SED data may be uploaded into the application from IVOA-compliant VOTable and FITS format files, or imported directly from the NASA Extragalactic Database (NED). Data written in unsupported formats may be converted for upload using the SED Importer tool which is bundled with the software.  Iris can write SED data files in one of the aforementioned supported file formats, as well as files for restoring custom fitting sessions.”
