The primaries have magnitudes in the range K=3.8 to 10.4, and the companions in the range K=6.4 to 12.1. The magnitude differences have a median value of 2.8, with the largest being 5.4. The projected separations are in the range 6 to 748 milliarcseconds and with a median of 18 milliarcseconds, or about 3 times less than the diffraction limit of the telescope.
