CMDs of the innermost (top left) and outermost ACS (top right) subfield and the four WFPC2 fields (middle and bottom) for NGC 1569. The dashed-dotted lines indicate the calculated TRGB values and the long-dashed lines show 50% completeness levels. The two boxes shown in the 10885/1 plot indicate adopted color and I-magnitude ranges for selecting RGB and carbon stars (see Sects. 3.3,  3.4 and 4.1 for details). Smaller plot symbols are used for the A1 subfield to avoid its saturation and make the different CMD features visible.
