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. |
