Two grade 1 binaries. Left: orbit for HIP 40167 = WDS 08122+1739 = ζ₁ Cnc. More than three laps of its 59.8 yr period have been completed by this pair, with components having V magnitudes of 5.50 and 6.11 and spectral types G4 IV and K0 IV, respectively. ΣM = 2.88 ± 0.18 M_⊙. Right: orbit for HIP 98001 = WDS 19550+4152. Five laps of its 29.5 yr period have been completed for this binary. The components have V magnitudes of 7.91 and 8.53 with spectral types G9 V and K2 V, respectively, and ΣM = 2.96  ±  0.31 M_⊙. Several position angles are changed by 180^∘, the circled points.
