Extracting Photometry Measurements from VizieR Catalogs
Résumé
Photometry measurements in astronomical catalogs cover a wide range of spectral bandpasses with many different photometric systems and units. The VizieR Catalog service has recently extended the standardized description of catalogs to include photometry . This includes the observed frequency and bandwidth in GHz and conversion of magnitudes and other units to flux densities in Jy. We present various prototype interfaces for extracting and combining photometry across multiple catalogs and discuss the uses and limitations of this service.
