Four‐panel figure of the DDO 53 showing the ACS footprint in blue with the chip gap direction in red over (a) the R‐band DSS image, (b) the color ACS image, and stellar density maps of (c) blue and (d) red stars as determined by their positions on the CMD. The blue stars have a color <0.6 and magnitude >60% completeness in F814W. The red stars are defined as ﹩0.6\leq \mathrm{color}\,\leq 3.0﹩ and a magnitude range between the TRGB and 60% completeness in F814W. The highest density regions are the red contours and the lowest are in purple.
