Relation between virial and Jacobi radii in Test 2. Top panel: comparison between the virial radius of the input NFW halo and the Jacobi radius recovered by ASOHF for all detected substructures. Colours encode the radial position of the substructure centre in the host halo (D) in units of the host virial radius The dotted red line corresponds to the identity relation, tight linear relation between the quotient position of the substructure.
