Properties of the LoTSS-DR2 RM catalog and of the ELAIS-N1 LOFAR Deep Field catalog.
| Catalog | Reference | Area | Resolution | νc | ∆ν | δϕ | σQU | NRM | NRG | Nz |
|---|---|---|---|---|---|---|---|---|---|---|
| (deg2) | (arcsec) | (MHz) | (MHz) | (rad m–2) | (µJy beam–1) | |||||
| LoTSS-DR2 RM | (1) | 5720 | 20 | 144 | 48 | 1.16 | 75 | 2461 | 1980 | 1783 |
| ELAIS-N1 | (2) | 25 | 6 | 146 | 63 | 0.9 | 20 | 33 | 31 | 31 |
Notes. (1) O’Sullivan et al. (2023). The quoted σQU nmoise value corresponds to the median detection threshold, 8 σQU = 0.6 mJy beam–1. (2) Paper I. The quoted noise value is the value measured at the center of the ELAIS-N1 field. νc is the central frequency, ∆ν is the bandwidth, δϕ is the resolution of the Faraday spectra, and σQU is the noise level in the Stokes Q and U Faraday cubes (Paper I). NRM is the number of entries in the RM catalogs. NRG is the number of radio galaxies associated with at least one RM value. Nz is the number of radio galaxies with a known redshift and associated with at least one RM value.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
