Source parameter space investigation with LENSINGGW: Mismatch study of a nonspinning compact binary. Each dot represents a pair of component masses in the ℳ_c − q plane, lensed by the galaxy plus the point-lens model presented by Diego et al. (2019). All other source parameters are fixed. The point-lens mass is M_L = 100 M_⊙, and is placed at the position of the macroimage formed by the galaxy. For each configuration, the mismatch between the lensed and unlensed GWs is displayed in a color map; darker colors denote larger mismatches (see the color bar at the right). A large mismatch is necessary to distinguish a lensed signal as such.
