HST ACS CMDs of both fields of Ho II and DDO 165 presented in ACS instrumental filters F555W and F814W, contoured by stellar density on the CMD. Regions of density less than 4 stars dmag⁻² (﹩0.1\times 0.1﹩ mag bins) are plotted as points. Contours are spaced by factors of 2 to show the detailed structure of the CMDs.
