Binary Stars Orbital Velocity?

The spectrum of the binary shows two FeI lines, one from each star. The lines oscillate about a mean wavelength of 527.1 nm with a period of 2.374 days. The maximum displacements from the mean are 0.129 nm for one star (Star 1) and 0.202 nm for the other (Star 2). The stars have circular orbits about their common centre of mass. I need to figure out the orbital speeds in kms-1 for each star relative to the centre of mass of the binary system. Any ideas?
