Accretion status as a function of binary separation. The gray shaded bars show the restricted sample, the combined shaded and hatched bars represent the full sample. One tick mark on the y-axis is equivalent to one binary. The classifications CC, WW, CW, and WC refer to binaries composed of classical and weak-line T Tauri stars with the first and second character describing the primary and secondary component. No systems with two accreting components were detected.
