[   4] A is a spectroscopic binary, spectrum G7.5IIIaCN-
       Fe0.5.
[   5] Psi Ser. AC: C is BD+02@2988. CE: E is BD+02@2987.
[   6] Alpha Ser. Variable?
[   7] Beta Ser. Proper motion of B -069 -058.
[   8] AB: B is BD+13@3063.
[   9] Nu Ser. B is BD-12@4724. Proper motion of B +021 +008.

[  12] AB: Theta (1) Ser. B is BD+04@3917, Theta (2) Ser.
       BC: This system analysed in detail by Teague (TEA01) who
       determined the source of the errors in all three historical
       measures (LBZ56, PRZ02, and KPR99 which actually belongs
       with the AC pair) of this system.
