Notes.

Local sidereal time.

System equivalent flux density (SEFD), estimated from time-differenced visibility in the frequency range 134–147 MHz. The SEFD measurements have been updated compared to the one published in LOFAR20, following an improved methodology.

Observation selected for analysis in redshift bin 8.3, 9.1, and/or 10.1.
