Examples of magnification maps for first approach. First row from the top: Standard scenario without PBHs and with 90% of mass in SDM. Second row: Non-standard scenario with 50% of mass in SDM and 45% of mass in PBHs with M_pbh ∼ 0.001 M_⊙. Third row: Non-standard scenario with 10% of mass in SDM and 81% of mass in PBHs with M_pbh ∼ 0.1 M_⊙. Fourth row: Non-standard scenario with 50% of mass in SDM and 45% of mass in PBHs with M_pbh ∼ 10 M_⊙. In all scenarios, the quasar source is of intermediate size (see the main text). The colour scale represents magnification values, with 2.66 and 0.56 being the macro-magnifications of A and B, respectively.
