Catalog Service: Spectral index for B3 radio sources
Description
Flux density measurements at 4730MHz are presented for a sample of 770 radio sources from the B3 catalogue with density S408>0.35Jy. For 429 of these sources flux density measurements at 1410MHz are also presented. The radio spectral indices derived are used to investigate the dependence of median spectral index on flux density

This is service that does not comply with any IVOA standard but instead provides access to special capabilities specific to this resource.
This is a standard IVOA service that takes as input an ADQL or PQL query and returns tabular data.
This is a standard IVOA service that takes as input a position in the sky and a radius and returns catalog records with positions within that radius.
