WMAP1 + MareNostrum Sim.
Correlation between optical depth τs=-ln Fs in the hydro spectra (smoothed at the BOSS resolution) and the smoothed DM overdensity (1+δs) at the same location along the line of sight for
different choice of DM smoothing scales. Here, spectra and DM density are both computed
in redshift-space (s-s).
