Examples of sources with a single extreme emission feature that is consistent with their z phot, classified in confidence Tier 1B. Photometry postage stamps show a continuum filter (top) and an extreme emission filter (bottom), with north up and east left. All postage stamps are 4″ in width and height. Panel (A): extreme emission in F444W consistent with Hβ + [O III] and a Lyman break between the F150W and F115W filters. Panel (B): extreme emission in F444W consistent with Hβ + [O III]. The images indicate at least one nearby companion. Panel (C): extreme emission in F410M consistent with Hβ + [O III]. While this EELG has a close neighbor in its image, this companion galaxy does not exhibit the same dramatic differences between continuum and emission-line filter morphologies as the EELG.
