The 1 column in color are computed by VizieR, and are not part of the original data.

Note: USNO-A2.0 contains 526,280,881 sources, and is based on a re-reduction of the Precision Measuring Machine (PMM) scans from POSS-I O and E plates (>=-18°) and SRC-J and ESO-R plates (<=-20°). USNO-A2.0 was created by Dave Monet () and collaborators at Flagstaff Station, U.S. Naval Observatory.
The major difference between USNO-A2.0 and its previous version USNO-A1.0 is that A1.0 used the Guide Star Catalog as its reference frame whereas A2.0 uses the ICRF as realized by the USNO ACT catalog (Urban et al. 1997). The VizieR search engine uses an on-line compressed version (3.6Gbytes) which was generated at CDS.

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).
