Abstract
We introduce our VLT-FLAMES Large Programme that has observed ∼800 early-type stars in the Galaxy and the Magellanic Clouds. The service-mode data sample a wide range of observational epochs, revealing a large number of massive binaries. In the course of disentangling the kinematics of these systems, cross-correlation techniques reveal the excellent wavelength-stability of the FLAMES spectra (±2 km s-1). This stability enables well-constrained orbital parameters to be found.
