[ 1] 5 Ser. AB: Mt. Wilson spectral types F5s, M0.
AD: See BDS and ADS for rectangular measures.
[ 2] 6 Ser. Possibly variable.
[ 3] Delta Ser. A premature orbit has been computed.
The primary is a Delta Scuti-type variable.
Measure of 1927.40 made by triangulation of multiple measures.
[ 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.
[ 10] B is BD-11@4410. Proper motion of B +009 +002.
[ 11] B is BD-15@4723. Proper motion of B -007 -059.
[ 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.
