VizieR Online Data Catalog: VLA imaging of the XMM-LSS/VIDEO deep field (Heywood+, 2020)

The observations were conducted using the VLA in B-configuration. A single 1.5h Scheduling Block (SB) was submitted for each of the 32 pointings, containing the necessary calibrator scans, as well as scans of the science target. The on-source observation time for each target pointing was 67.5m, with 3s per correlator integration. The correlator was configured in standard wide-band continuum mode, with 0.994-2.018GHz of spectral coverage split up into 16MHzx64MHz spectral windows (SPWs) for a total of 1024 channels.

The package PROFOUND (Robotham et al. 2018MNRAS.476.3137R) was used to generate an associated source catalogue from the total intensity mosaic. Although designed for optical/near-infrared surveys, PROFOUND has been shown to be able to successfully model radio emission (Hale et al. 2019MNRAS.487.3971H) for sources of different morphologies. As PROFOUND does attempt to fit to any particular morphology (e.g. 2D Gaussians), complex morphologies (e.g. AGNs with extended jets) may be more faithfully modelled.

Using PROFOUND we derived a catalogue containing 5762 sources from the total intensity mosaic. The properties of our final sample of radio sources are shown in Table 1.
