In the event the images were taken in vertical angle mode, de-rotation of the images was performed to place each frame back into position angle mode. Note (2): SPOCS catalog used to obtain stellar mass measurement of the primary star and infer the dynamical minimum mass of the companion. -------------------------------------------------------------------------------- HD1293 AB H 3.05 0.120 3.08 0.14 126.77 1.84 185.20 0.61 24.74 0.99 68.56 1.13 0.57 0.43 1.05 0.06 HD1388 AB K_cont_ 5.87 0.220 8.71 0.22 1677.18 2.40 319.70 0.09 45.20 0.09 26.10 0.25 0.75 0.06 0.13 0.01 HD4406 AB K' 0.43 0.010 1.33 0.03 75.96 4.98 246.79 3.77 9.46 0.63 18.20 1.68 0.02 0.01 1.40 0.01 HD6558 AB K' 4.54 0.010 6.84 0.02 4777.50 2.93 286.20 0.06 392.23 1.93 -37.28 0.88 79.38 4.92 0.33 0.01 HIP46199 AB J 1.79 0.230 7.13 0.2 411.40 1.20 288.69 0.68 8.08 0.60 -152.10 2.21 0.18 0.03 0.41 0.03 HIP46199 AB K' 1.16 0.620 5.94 0.46 412.30 1.00 288.56 0.68 8.10 0.60 0.48 0.07 HD88986 AB K' 4.28 0.010 6.57 0.02 1521.11 1.66 59.74 0.09 50.65 0.08 -1.65 0.07 0.06 0.01 0.37 0.01 HD105618 AB K_cont_ 5.20 0.100 7.99 0.1 1040.08 3.99 316.75 0.22 73.05 0.38 3.36 0.40 0.25 0.06 0.19 0.01 HD131509 AB J_cont_ 4.26 0.030 6.15 0.04 589.07 1.08 35.78 0.14 45.63 0.20 -7.73 0.10 0.26 0.35 0.57 0.01 HD131509 AB K_cont_ 3.95 0.050 5.29 0.05 598.75 0.46 35.99 0.06 46.38 0.18 0.58 0.01 HD156826 AB J_cont_ 5.71 0.330 7.34 0.33 1720.28 2.92 338.78 0.04 82.16 0.21 -9.80 0.16 1.41 0.39 0.38 0.05 HD156826 AB K_cont_ 4.53 0.070 5.40 0.07 1721.39 0.47 338.77 0.01 82.21 0.16 0.56 0.01 HD156828 AC J_cont_ 4.97 0.130 6.61 0.13 1939.54 2.10 341.91 0.04 92.63 0.20 1.79 0.40 0.50 0.02 HD156828 AC K_cont_ 4.65 0.080 5.52 0.08 1940.01 0.66 341.88 0.01 92.66 0.18 0.54 0.01 HD217165 AB K_cont_ 2.98 0.010 6.02 0.02 318.76 0.37 73.88 0.17 14.02 0.04 -365.60 0.54 0.27 0.34 0.46 0.01
