discov_num notes refcode
STT 157 Quadrant noted as definite on first and last night. Yet no change can
have taken place since Rabe's and Baize's measures in 1938 and 1942. VBs1954
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 14.45 +/- 8.14, 4.44, and 2.09 Msun, respectively. Mlk2012
