Layout of the MUSE-Wide regions with the galaxy sample represented by red circles. Left: blue dots correspond to HST/WFC3 objects from the 3D-HST survey in the GOODS-S region brighter than 24 mag in the F160W band. The black, orange, green, purple, and blue contours approximately delimit the candels-cdfs, HUDF09 parallel, UDF mosaic, UDF-10, and MXDF regions, respectively. Right: sample galaxies (red symbols) in the candels-cosmos fields. The black line encloses the area covered by the MUSE-Wide survey. The red and blue symbols are the same as in the left panel. For more details about the fields, see Sect. 2.
