Cross-correlation of the variance of the Lyα flux and CMB convergence as a function of redshift for the three different cosmological models with massive neutrinos shown in Table 4. Black, orange, and red (with 1σ) error bars refer to Σ  m _ν(eV) = 0.54, 0.4, 0.15, respectively. The black dashed line shows the prediction for a massless neutrino cosmology consistent with WMAP-5 data. Four different cases are reported here for Planck+BOSS (top left), Planck + BigBOSS (bottom left), ACTPOL+BOSS (top right), and ACTPOL+BigBOSS (bottom right). The redshift evolution of A is taken into account here.
