The optical spectrum of V 818 Sco does not show strong sharp stellar absorption
lines like those present in the other identified binary X - ray sources . Instead , the
spectrum exhibits ( 155 , 156 , 161 - 164 ) a very blue continuum with weak ...

The radial velocities inferred from Hell 24686 give weak evidence [ 171 ] that the
phase of closest approach of the region emitting this line may agree with the
phase of maximum light . 8o5 . Distance . - The distance to Sco X - 1 is uncertain .
