Simulation workflow that we adopt for generating the mock lensed quasar images. The cutouts are based on the HSC images with 72 × 72 pixels wide (≈12″ on a side). The real galaxy, acting as a lens, is shown in the upper left panel. On the other hand, the quasar, which serves as a background source, is depicted in the lower left panel as a Gaussian light profile. The deflected source’s light convolved with the respective HSC PSF model is shown in the lower middle panel, which is determined based on the associated lens arrangement. Ultimately, we paint the multiply-imaged sources on top of the galaxy image and display it in the upper right panel. Below each panel, the lens parameters (in arcseconds, β and θ_E) and the photometry is reported. In this case, we construct mock images for all HSC bandpasses – namely, grizy bands.
