VizieR Online Data Catalog: The 1.266GHz MeerKAT DEEP2 component catalog (Matthews+, 2021)
Abstract
The 1.266GHz DEEP2 image (Mauch+ 2020ApJ...888...61M) covers the {Theta}1/2=69.2' diameter half-power circle of the South African Radio Astronomy Observatory's (SARAO) MeerKAT array primary beam centered on RAJ2000=04:13:26.4s, DEJ2000=-80:00:00. Its point-source response is a {Theta}1/2=7.6" full width at half maximum (FWHM) Gaussian, and the rms noise is σn=0.56+/-0.01μJy/beam at the pointing center. The wideband DEEP2 image is the average of 14 narrow subband images (with central frequency from 908.010 to 1656.2MHz) weighted to maximize the signal-to-noise ratio (S/N) of sources with spectral index α=-0.7.
In this work, we presented source counts in the eight decades of flux density from S=0.25uJy to S=25Jy using the MeerKAT DEEP2 field and archival NVSS data. (2 data files).- Publication:
