Fig. 1.

Direct F444W stamps, Hα maps, 2D spectra, and 1D spectra of four sources in the FRESCO Hα catalog with different quality flags. Top left: single-component galaxy with q = 3. Top right: multi-component galaxy with q = 3. Bottom left: single-component with q = 2. Bottom right: single-component with q = 1. For the analysis of this paper, we only include sources with q ≥ 1.75.
