Query: New distance and depth estimates from observations of eclipsing binaries
  in the SMC   A sample of 33 eclipsing binaries observed in a field of the SMC with
FLAMES@VLT is presented. The radial velocity curves obtained, together with
existing OGLE light curves, allowed the determination of all stellar and
orbital parameters of these binary systems. The mean distance modulus of the
observed part of the SMC is 19.05, based on the 26 most reliable systems.
Assuming an average error of 0.1 mag on the distance modulus to an individual
system, and a gaussian distribution of the distance moduli, we obtain a 2-sigma
depth of 0.36 mag or 10.6 kpc. Some results on the kinematics of the binary
stars and of the H II gas are also given.
