Notes.

(a)

A redshift of z = 5.24 ± 0.01 is obtained from fitting the O I and Si IV emission lines and a redshift of 5.34 ± 0.02 is obtained from template fitting.

(b)

These sources are not included in the FIRST or VLASS catalogue, but are marginally detected (3–6σ) in the images. The values given here are the peak fluxes including a 15% correction for the VLASS measurements.

(c)

These spectral indices are calculated from the LOFAR and VLASS survey measurements (). The full table is available in electronic form at the CDS.

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.
