WDS 17360+2100 STF 2190 AB (HD 159834) : NOTES
 
 
discov_num notes refcode
STF2190 A is a spectroscopic binary.
Herschel observed this pair and another nearby pair of similar rho and HJ_1833c
theta and same primary and secondary magnitudes he designated HJ 2807.
Offset from his STF2190 coordinates shows no bright star at location
of HJ 2807, however. Burnham says HJ 2807 is "undoubtedly identical Bu_1906
with STF2190" (= BDS 8082). Herschel's 1830.47 measure was accordingly
reassigned to STF2190. Gauchet disagrees with Burnham, but his Gau1925
separation does not agree with Herschel's and his coordinates precess
to location of a 7th magnitude star (BD+20@3531) 1.5m east of
Herschel's. Separation and magnitudes of this pair, designated
GAU 21, agree with Gauchet's, although the quadrant is reversed.
