J/A+A/501/801     CBI sample at 4.85GHz and 10.45GHz    (Angelakis+, 2009)

Multi-frequency measurements of the NVSS foreground sources in the Cosmic Background Imager fields. I. Data release. Angelakis E., Kraus A., Readhead A.C.S., Zensus J.A., Bustos R., Krichbaum T.P., Witzel A., Pearson T.J. <Astron. Astrophys. 501, 801 (2009)> =2009A&A...501..801A
ADC_Keywords: Radio sources Keywords: radio continuum: general - catalogs - galaxies: active - microwave background Abstract: We present the results of the flux density measurements at 4.85GHz and 10.45GHz of a sample of 5998 NVSS radio sources with the Effelsberg 100m telescope. The initial motivation was the need to identify the NVSS radio sources that could potentially contribute significant contaminating flux in the frequency range at which the Cosmic Background Imager experiment operated. Description: This table includes the Effelsberg measured flux densities at 4.85 and 10.45GHz along with the NVSS ones of all the sources that do not suffer from confusion and the computed spectral indices (it is assumed that S∼nualpha).

Note (2): The detection threshold is 5σ so when there is no detection, an upper limit of 5σ is given after the symbol "<". Note (3): Empty field when there is no detection. Note (4): available when source is detected at both 4.85 and 10.45GHz.
