Extended Data Table 1 Measured properties of confirmed members of XLSSC 122 and z = 1.93 structure

From: Spectroscopic confirmation of a mature galaxy cluster at a redshift of 2

  1. Magnitudes are measured using the F140W filter and employ a Kron-type aperture. Colours are expressed as F105W − F140W magnitudes and are measured in 0.8-arcsecond circular apertures. The notes refer to gold (G) and silver (S) cluster members in addition to galaxies located in the foreground (F) structure; E refers to an emission line galaxy. Decl., declination. ID numbers are output from SExtractor.
