VizieR Online Data Catalog: GLOSTAR. Radio Source Catalogue. II. (Dzib+, 2023)
Abstract
As part of the GLOSTAR survey, the VLA in its B- and Dconfiguration was used to observe a large portion of the Galactic plane in the C-band. In this paper we present the B-array observations covering the area within 28°<=l<=36° and |b|<1°, which we previously investigated using data obtained in the D-configuration (Medina et al., 2019A&A...627A.175M, Cat. J/A+A/627/A175). Using a combination of automatic source extraction with BLOBCAT (Hales et al., 2012MNRAS.425..979H) and visual inspection we have identified 3325 radio sources.
The catalog of these radio sources is divided in two parts. The catalog of highly reliable radio sources contains 1457 entries. Detailed properties of these sources are given, such as the positions, the signal-to-noise-ratio, integrated and peak fluxes, the ratio between these two values (also known as the Y-factor), the effective radii, and the spectral indices. The weak source catalog lists 1866 sources with a signal-to-noise ratio between 5 to 7. Only their basic properties such as positions, the signal-to-noise ratio, integrated and peak fluxes are given.
