Notes. Here SI is the mid-point integrated flux density of each bin, and the SI range gives the flux-density limits of the bin. The Type column indicates the image used for the measurements, where E−N1, MC, and MR correspond to the ELAIS-N1 image, deep LoTSS-DR3 mosaics with completeness corrections, and all LoTSS-DR3 mosaics without any completeness correction, respectively. N is the number of sources detected in a given flux-density bin, Area is the sky area used for the measurement, F is the fraction of sources recovered in a particular flux density bin compared to the number injected in that bin during the simulations, and Counts gives the Euclidean-normalised 144 MHz differential source count after correcting for F. The errors Eg, Es, and Ep represent the field-to-field variations (or 14% for ELAIS-N1), the effect of systematic flux-density scale uncertainties (9% for ELAIS-N1 and 2% for LoTSS-DR3), and the Poisson uncertainty on the number of detected sources, respectively.

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.
