Profile of the estimated tangential reduced shear for RCS2 J2327, based on the matched HAWK-I and ACS ellipticity catalogue, employing the HAWK-I+LBC colour selection and uniform weights. We show all radial bins containing at least five galaxies. The solid (open) points are based on the HAWK-I (ACS) ellipticity measurements, shown with an offset of + 30 kpc ( − 30 kpc) for clarity. The red open triangles indicate the difference between the two estimates with error bars determined by bootstrapping the sample. Matched data are only available in the central ACS pointing and near the corners of the HAWK-I field of view. The resulting smaller area and lower source density leads to more noisy data compared to the analysis of the full HAWK-I+LBC-based catalogue (compare Fig. 12) and introduces the gap at intermediate radii.
