Image Details
Caption: Figure 3.
Source plane modeling using Lenstruction (L. Yang et al. 2020). From the top left, we plot the observed image (in F200W), the source model, the best-fit image model (after lensing and PSF convolution have been applied), and normalized residuals. The source was modeled using an underlying galaxy component G and three small clumps (#1–3) modeled using Gaussian profiles.
