Image Details
Caption: Figure 5.
Cutout images (4﹩\mathop{.}\limits{^{\prime\prime} }﹩8 × 4﹩\mathop{.}\limits{^{\prime\prime} }﹩8) of the Cosmic Gems Arc in the NIRCam F150W and detection (F277W + F356W + F444W) image. The source segments, outlined in gold, were defined from the detection image, which has a very broad PSF. The Kron ellipse, shown in red, was defined from the central moments of the flux distribution within the source segments. In the F150W image, we also label the two mirrored images of the arc, Images 1 and 2, as well as the star clusters A through E analyzed in detail by A. Adamo et al. (2024).
