Projected separation plotted against mass of the lower mass WD in the binary for 10% (panel a) and 95% (panel b) initial binary fraction for the whole parameter space. The numbers inside the square brackets in the legends show the total number of WD binaries in the runs. The different colors correspond to the different datasets: orange for escapers, blue for standalone binaries, red for in-cluster primordial binaries, green for in-cluster dynamically formed binaries, dark red for observations of close binaries, and purple for observations of wide binaries. In addition, we have four different types of markers: stars for observed WDs, circles for helium WDs, diamonds for carbon oxygen WDs, pluses for oxygen neon WDs.
