Description:
Photometry in the Geneva systems and radial velocities are used to
determine the fundamental parameters of three eclipsing binaries, two
of which having been classified as chemically peculiar and the third
having relatively narrow lines.
For a description of the Geneva photometric system, see e.g. GCPD/13
