Rest-UV (blue) and rest-optical (orange) continuum fitting of RUBIES-EGS-42046 (top) and RUBIES-UDS-934230 (bottom) from PRISM spectroscopy (solid) and NIRCam photometry (dashed). In the insets are the 0.5″ × 0.5″ NIRCam F444W/F277W/F150W RGB cutouts of the sources. We emphasize that spectroscopic rest-optical continuum fitting can mitigate the effect of strong emission lines, but can suffer in S/N in the rest-UV where the spectrum is fainter or cannot capture extended rest-UV emission due to slit losses. RUBIES-EGS-42046 is identified as a spectroscopic v-shape, while RUBIES-UDS-934230 is not despite a red photometric rest-optical color.
