There are now $\\gtrsim10$ different Ly$\\alpha$ reconstruction pipelines using different methodologies to predict the Ly$\\alpha$ line flux from correlations with the spectral information redward of Ly$\\alpha$. However, there have been few attempts to directly compare the performance of these pipelines. Therefore, we devised a blind QSO challenge to compare these reconstruction pipelines on a uniform set of objects.
