1.VIII/85A/spectra(c)The parameters of the radio spectra[image]
spectrum
(631736 rows)
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).
2.VIII/85A/waste(c)Source parameters based on positional cross-id[spectrum] (1497216 rows)
