CORS Baade-Wesselink distance to the LMC NGC 1866 blue populous cluster
  We used Optical, Near Infrared photometry and radial velocity data for a
sample of 11 Cepheids belonging to the young LMC blue populous cluster NGC 1866
to estimate their radii and distances on the basis of the CORS Baade-Wesselink
method. This technique, based on an accurate calibration of the surface
brightness as a function of (U-B), (V-K) colors, allows us to estimate,
simultaneously, the linear radius and the angular diameter of Cepheid
variables, and consequently to derive their distance. A rigorous error estimate
on radius and distances was derived by using Monte Carlo simulations. Our
analysis gives a distance modulus for NGC 1866 of 18.51+/-0.03 mag, which is in
agreement with several independent results.
