Distance, orbital period Porb, and F146Vega magnitude distributions of NS+star and BH+star binaries in the GBTDS contiguous fields. All binaries with F146Vega < 23.5 mag are shown in the solid lines; binaries with poor single-star goodness of fit (z1s > 5) are shown in dashed lines. Because NSs are less massive than BHs, they have smaller photocenter wobbles and are preferentially found at closer distances. Note that we have generated 10× as many NS and BH binaries as in our fiducial model above to enable better visualization of the statistics.
