TL;DR
This paper presents a new 4.85 GHz survey of bright radio sources using the Effelsberg telescope, enhancing existing sky coverage and linking to WMAP data, with follow-up observations at 8.4 GHz to improve catalog completeness.
Contribution
It introduces a new survey that improves the completeness of bright radio source catalogs at 4.85 GHz and assesses its effectiveness in supplementing existing surveys like CRATES.
Findings
Enhanced sky coverage of bright radio sources.
Improved correlation with WMAP point source catalog.
Demonstrated effectiveness of follow-up observations at 8.4 GHz.
Abstract
We describe a 4.85 GHz survey of bright, flat-spectrum radio sources conducted with the Effelsberg 100 m telescope in an attempt to improve the completeness of existing surveys, such as CRATES. We report the results of these observations and of follow-up 8.4 GHz observations with the VLA of a subset of the sample. We comment on the connection to the WMAP point source catalog and on the survey's effectiveness at supplementing the CRATES sky coverage.
