Notes. 1. Integral magnitudes of the whole system A outside binary eclipses of the Ac1+Ac2 eclipsing binary are V = 624, B = 638, and U = 554 according to our standard Johnson photometry. The following infrared magnitudes were obtained by Cutri et al. (2003) at JD 2450893.6074, i.e. close to a quadrature of the Ac1/Ac2 pair (orbital phase 0.815 from the primary minimum): J = 5551, H = 5393, and K = 5252; 2. Sana et al. (2014) resolved component A into very close components Aa and Ac (called A-D by them), separated by only 003. An accurate position of this pair was then obtained by Sanchez-Bermudez et al. (2017); 3. At 100 from Aa+Ac. Discovered by ESA (1997) and later observed by Tokovinin et al. (2010, 2015, 2018), Hartkopf et al. (2012) and Sana et al. (2014); 4. At 073 from Aa+Ac. First reported by Reggiani et al. (2020) and Rainot et al. (2020); 5. At an angular distance of 707 from A. First noted by Dawson (1918) and the latest observation by Knapp & Nanson (2018) shows no change in its position; 6. At 880 from A. Reported by Voûte (1955) (we note the correction of the position angle in Voûte 1956) and also observed by Curelaru (2017) and Knapp & Nanson (2018). The latter authors identified these components in the Gaia catalogue and transformed the Gaia magnitude to Johnson V; 7. Reported by Sana et al. (2014) (and called E by them). At a distance of 258±009 from Aa+Ac.
