Reconstructing the intrinsic Ly�ñ line flux from high-z QSOs can place constraints on the neutral hydrogen content of the intergalactic medium during reionisation. There are now â?ó10 different Ly�ñ reconstruction pipelines using different methodologies to predict the Ly�ñ line flux from correlations with the spectral information redward of Ly�ñ. 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. Each author was provided de-identified, observed rest-frame QSO spectra with spectral information only redward of 1260�? rest-frame to ensure unbiased reconstruction. We constructed two samples of 30 QSOs, from X-Shooter and SDSS both spanning 3.5 Download TeX format |
