1 Otero, Sebastian Alberto Min II= 4.88 V. The system HUB 11 = eta Mus only exists in the WDS, corresponding to A and B components (B is 2.5" apart and has G= 11.43). The "B" component in the CCDM is the common proper motion companion eta Mus C = WDS J13152-6754C (sep. 58"). This has caused many confusions in the literature (including the TDSC). (SIMBAD).
