VizieR Online Data Catalog: Polarized point sources in LOTSS-HETDEX (Van Eck+, 2018)

Abstract

Visibility data taken from LOTSS, imaged in polarization, and had RM synthesis applied. Resulting RM spectra were searched for polarization peaks. Detected peaks that were determined to not be foreground or instrumental effects were collected in this catalog. Source locations (for peak searches) were selected from TGSS-ADR1 (J/A+A/598/A78). <P />Due to overlap between fields, some sources were detected multiple times, as recorded in the Ndet column. <P />Polarized sources were cross-matched with the high-resolution LOTSS images (Shimwell+, in prep), and WISE and PanSTARRS images, which were used to determine the source classification and morphology. <P />(1 data file).
