 Phase-resolved spectroscopy of 4 high-mass X-ray binaries, aimed at 
measuring the mass of the neutron star companion from the radial-velocity 
curve of the OB star. 

 The success of the program depends on the full coverage of the orbital 
period of each object. 12 OBs have been provided for each target, and all 
have an attached ThAr. Spectra do not need to be obtained during just one 
orbit of the system. A table listing all the dates suitable for the entire 
P68 has been provided (phasetbl.ps).  

 The PI has also specified within which accuracy all the phases should be 
observed: this depends on the object - please cf README file for a wealth 
of details.
