GalCat application GUI created in IDL. The catalog of ALFALFA sources is displayed as a list at top left. For each source selected from that list, a summary is presented in the interface, including the measured parameters (top center), the isophotal fits (bottom left), the extracted “postage stamp” spectrum and its normalized weight at each spectral point (bottom center), and the optical image (bottom right). The top right panel offers the possibility to modify parameters as necessary.
