cds-question@unistra.frradio-sourcesinterferometryastronomical-object-identificationWe present observations from the Precision Array for Probing the Epoch of Reionization (PAPER) in South Africa, observed in 2010 May and September. Using two nights of drift scanning with PAPER's 60{deg} FWHM beam we have made a map covering the entire sky below +10{deg} declination with an effective center frequency of 145MHz, a 70MHz bandwidth, and a resolution of 26'. A 4800deg^2^ region of this large map with the lowest Galactic emission reaches an rms of 0.7Jy. We establish an absolute flux scale using sources from the 160MHz Culgoora catalog (Cat. VIII/35). Using the 408MHz Molonglo Reference Catalog (MRC, Cat. VIII/16) as a finding survey, we identify counterparts to 480 sources in our maps and compare our fluxes to the MRC and to 332 sources in the Culgoora catalog. For both catalogs, the ratio of PAPER to catalog flux averages to 1, with a standard deviation of 50%. This measured variation is consistent with comparisons between independent catalogs observed at different bands. The PAPER data represent new 145MHz flux measurements for a large number of sources in the band expected to encompass cosmic reionization and represents a significant step toward establishing a model for removing foregrounds to the reionization signal.2011ApJ...734L..34Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/734/L34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/35 : Radio Sources observed with Culgoora Circular Array (Slee 1995)VIII/16 : Molonglo Reference Catalogue of Radio Sources (Large+ 1991)VIII/85 : SPECFIND V2.0 Catalog of radio continuum spectra (Vollmer+ 2009)VIII/79 : The VLA Low-frequency Sky Survey at 74MHz (Cohen+ 2007)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/18 : 6C Survey of radio sources I.
