| VIII/104/spectra | SPECFIND V3.0 Catalog of radio continuum spectra (Stein+, 2021) The parameters of the radio spectra image (1658207 rows) | recno=390611 |
Note: 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).
