Comparison of the best-fit Lyα halo scale lengths of common objects from the deeper udf-10 data cube (≈30 h) and the shallower mosaic data cube (10 h) with reliable halo measurements (15 objects, see Sect. 4.3.2). Left: difference between the Lyα halo scale lengths, plotted as a function of the Lyα S/N from the mosaic data cube. The S/N is calculated in a fixed aperture corresponding to the CoG radius r_CoG (see Sect. 5.3.2). The median difference is ≲0.1 kpc. The dashed red line shows the S/N cut of 6 imposed on our sample (see Sect. 2.2). Right: difference between scale lengths, plotted against the total Lyα flux measured in the mosaic data cube. The red, orange, and green points correspond to the objects shown as examples in Fig. A.2. The corresponding MUSE IDs are indicated.
