A New Measurement of the Mean Transmitted Flux in the Lyman-alpha and Lyman-beta Forest

Jiani Ding, Piero Madau, J. Xavier Prochaska

We present new measurements of the mean transmitted flux in the hydrogen Ly$\hat{\mathrm{I}}\pm$ and a relative transmitted flux measurement in Ly${\hat{\mathrm{I}}}^2$ using 27,008 quasar spectra from the F…
