The column SED is a link to a plot of the radio spectrum, and the column Radio+Opt is a link to an Aladin preview. The SED plot contains points from the cross-identification (spectra; red), from the waste basket (waste; yellow), and the fitted radio spectra as lines. The Aladin preview contains a DSS image together with NVSS contours (blue) and the points and associated beams of the radio spectrum (red); points and beams of the sources from the waste basket are hidden but can be made visible by clicking on the corresponding plane (yellow).
