First alternative colour selection for galaxy clusters at redshift z ∼ 1.2. The selected source galaxies are at redshift z ≳ 1.3. We display galaxies based on their photometry from S14 in the GOODS-South field. Top: First selection step in the VIJ plane for bright galaxies on the left and faint galaxies on the right. Bottom: Second selection step in the UVJ plane for bright galaxies on the left and faint galaxies on the right. The solid black lines indicate cuts applied for bright galaxies, the dashed black lines show cuts for faint galaxies. Galaxies below the diagonal grey line are recovered in both the bright and the faint regime.
