Survey completeness maps obtained considering an additional extinction factor A_L′ = 1.0 mag. The three plots represent maps when assuming R_p = 2, 3, 5 R_J (left, middle and right panels, respectively). Solid contours limit the areas with completeness 2, 10 and 20, while dotted lines are reported from Fig. 8 and limit the same detection probability values when no extinction effects are included, thus allowing the direct comparison between the two cases.
