VIII/104/spectra
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).
