Caption: Figure 2.
PEARLS NIRCam image of the IRAC Dark Field (JWIDF) Epoch-1 at the north Ecliptic pole. Filter F150W is rendered as blue, F200W as green, and F356W+F444W as red using a log scaling (e.g., Lupton et al. 2004; Coe 2015). This 2040 × 3644 pixel section covers 61.″2 × 109.″3, and image orientation is shown by the labeled arrows. Areas with remaining wisps and snowball imprints were masked before making object catalogs and counts. (Please magnify all PDF images to see details.)
