Note
There are the separate single-component solutions.
For primary: P=3.4142765(fixed), T0=48259.329(+-0.006), K1=232.7(+-1.9) km/s,
V0=-12.1(+-1.5) km/s, rms1=4.8 km/s
For secondary: P=3.4142765(fixed), T0=48261.043(+-0.005), K2=256.5(+-1.8) km/s,
V0=-10.2(+-1.4) km/s, rms2=4.6 km/s
The radial velocities were taken from the archive of IUE observations.
The measured velocities are close to absolute values.
