cds-question@unistra.frradio-sourcessurveysWe present one of the deepest radio continuum surveys to date at a wavelength >~1m. The observations were taken with the VLA at 324.5MHz covering a region of the SWIRE Spitzer Legacy survey, centered at 10:46:00, +59:01:00 (J2000). The data reduction and analysis are described and an electronic catalog of the sources detected above 5{sigma} is presented. We also discuss the observed angular size distribution for the sample. Using our deeper 20cm survey of the same field, we calculate spectral indices for sources detected in both surveys.2009AJ....137.4846Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/137/4846CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/136/1889 : The deep SWIRE field I.
