Results from the modeling of the lensed arclet LAP1 using our forward-modeling procedure. The top-left panel shows the co-added flux of the Balmer lines (Hγ + Hβ + Hα) from the NIRSpec IFS datacube, where the blue circles indicate the position of the B1,2 mirror images and the red curve is the critical line corresponding to a source redshift z = 6.64 passing through the merged A1,2 images. The top-mid panel shows the corresponding model image; the inset shows the source plane configuration of A and B, where we also indicate the physical scale and the caustic line. The top-right panel shows the normalized residuals, (Data − Model)/σ. The bottom panels similarly show the GravityFM modeling of the VLT/MUSE Lyα image, with overlaid Lyα emission contours (in yellow) obtained from the NIRSpec datacube.
