Galaxy connectivity as a function of stellar mass, shown for different redshift bins (columns). Redshift bin edges were chosen to contain approximately the same number of observed galaxies. The black, magenta, and blue curves correspond to the mean connectivity measured from the observed JPAS+DESI galaxies, the mock galaxies, and the ideal 3D connectivity measurements, respectively (see details in Sect. 5.1). Averages based on fewer than five galaxies are not shown. The error bars correspond to the 1σ dispersion of the data points around the mean connectivity within a given mass bin.
