An example of the CMD filter that is applied to the photometric catalog derived from the WIYN ODI imaging of each UCHVC field in order to select stars with properties expected for a dwarf galaxy at a given distance (see Section 4.1). Black points are point sources located within the images, and red points are those that coincide with the location of the filter given their g and i magnitudes and associated 1σ uncertainties. Error bars showing the typical photometric uncertainties at various magnitudes are plotted in blue on the right-hand side. The filter shown in this example corresponds to a distance of 400 kpc.
