This parameter was introduced to subdivide the SAURON sample of early type galaxies in so called fast $\\lambda_R > 0.1$ and slow rotators $\\lambda_R < 0.1$. Tests on merger remnants reveal that $\\lambda_R$ is a robust indicator of the true angular momentum content in elliptical galaxies. We find the same range of $\\lambda_R$ values in our merger remnants as in the SAURON galaxies.
