Top left: difference in F435W−F606W colour between S14 and R15 as a function of the F775W magnitude in R15. The solid line shows the median in bins containing 151 objects each, with the dashed lines enclosing 68% of all objects. The horizontal dotted line shows the zero level to help comparisons. Top right: same, but for the F606W−F775W. Bottom left: same for the F775W−F850lp colour. Bottom right: in black the number of objects in the R15 catalogue over the MUSE mosaic field as a function of F775W, while the blue histogram shows the number of objects that are in the matched catalogue of R15 and S14. The histograms are both normalised to unit area to ease comparison.
