A comparison with the AT20G bright source sample, with a completeness limit of 0.5Jy and accurate flux measurements at 20GHz, close to the lowest frequency of WMAP maps, has allowed us to assess the completeness and the reliability of the samples detected with the two approaches, as well as the accuracy of flux and error estimates, and their variations across the sky. Description: The NEWPS catalogue have been obtained by combining blind and non-blind detections performed with the MHW2 filter on the 5-year Wilkinson Microwave Anisotropy Probe (WMAP) total intensity maps at 23, 33, 41, and 61GHz. According to the SNR ratio that have been used to select the objects we have generated a SNR>5 catalogue. A further selection have been applied according to the noise in the source position being smaller than 1.5 times median noise in the map as described by Massardi et al. (2008, Cat. J/MNRAS/384/775) that generated the catalogue that counts 516 sources. These sources have been queried in the Nasa Exragalactic Database (NED) for an identification in other catalogues and a value of redshift. A more detailed description is provided in the paper and at the NEWPS website at where all data products, and updates were released as soon as they were produced and verified. File Summary:
