1 Hinzel, David H. Optical fluxes distributed bimodally around mean orbital light curve with both high and low states showing the same modulation.
2 Otero, Sebastian Alberto Normally between 12.0 - 13.5 V (ASAS-3)
3 GCVS Team Sco X-1. SB. Var X-ray and multi-component radio source. Lx/Lbol = 300 - 1000. The epoch of Min is given for the periodic component of the light variation (A ~0.25m). Flickering and flares up to 1m with time scale from dozens of seconds to minutes. The mean brightness level decreased in the middle of 1960-es by 0.3m-0.4m. The spectrum with blue continuum and H, HeI, HeII, CIII, NIII emissions.
