Image Details
Caption: Figure 1.
HST WFC3-UVIS F656N mosaic image (left), program footprint of IC 348 (middle), and map of 229 known members of IC 348 within the field of view of our observations (right). North is up, and east is to the left. The HST F656N mosaic composite image is aligned with the reproject package in Python, which combines World Coordinate System information from the individual image, subsequently reprojecting and combining them into a single mosaic. In the footprint panel, lighter shades correspond to single-orbit coverage, while darker shades indicate overlapping regions observed in multiple orbits. Each HST orbit includes two sets of observations with a maximum allowed midorbit maneuver of 120″ without target reacquisition. In the map panel, the marker size schematically represents stellar mass.
