Figure 4 from Tam et al. (2020) showing the large scale-structure in a total region of 30 × 30 arcmin² around MS 0451. The positions of RPS candidates of Samples 1a, 1b, 1c, and 1d are respectively shown as green, cyan, blue and red circles. The RPS candidates of Sample 2 with grades J = 1 to 3 are shown as magenta crosses, and those with J = 4 and 5 with magenta squares. The white cross indicates the position of the cluster centre. North is up and east is left.
