Shear radial profiles as a function of cluster-centric projected distance for the primary (upper panel) and the secondary component (bottom panel) of A1204, identified by de los Rios et al. (2016). The solid and the dashed lines represent the best fit of SIS and NFW profiles, respectively, with the fitted parameters given in the right-upper corner. The points and crossings show the tangential and cross ellipticity components of the selected background galaxies, averaged in annular bins, respectively. Error bars are computed according to Eq. (2).
