Abstract
The parallaxes determined by Lacy (1979) by means of eclipsing binaries met hod are compared with the Hipparcos parallaxes for 19 systems. The residual scatter of the distance moduli inferred from eclipsing binaries method - a fter allowing for known errors as given by Lacy and Hipparcos-is equal to 0 .18 mag. It decreases to 0.08 mag when obviously not fitting semi-detached systems and systems with chromospheric activity of components;are removed f rom the sample.
