Reig, Fabregat & Coe (1997) plotted the equivalent width of H emission against the orbital period for several Be star/X-ray binary systems, and find a correlation. If instead of the equivalent width, which is a relative quantity, the luminosity of H emission, which is an absolute quantity, is used the correlation is not found.
Key words: stars: emission-line, Be X-rays: stars
