Selected high density regions for CARLAJ0958-2904 at z = 1.392, CARLAJ0116-2052 at z = 1.425, CARLAJ1103+3449 at z = 1.444, CARLAJ1131-2705 at z = 1.446, CARLAJ2355-0002 at z = 1.49, and CARLAJ1129+0951 at z = 1.528. Passive and active galaxies are shown in red and blue, respectively. We use pink when we cannot separate passive and active galaxies, either because the cluster was not observed in four bandpasses or because the galaxy was not detected in one of the four bandpasses. The ETGs are shown as circles. LTG are shown as squares (disks) and diamonds (irregulars). The cluster spectroscopic members are marked by a small yellow circle; when they are black they are not included in our magnitude, colour and spatial selection, but are shown to better explain our overdensity selection. The RLQ and HzRG are shown as stars and triangles, respectively.
