CoreForest.tau_GP(gamma_bg, delta, temp, redshifts)[source]#

Calculating the lyman-alpha optical depth in each pixel using the fluctuating GP approximation.

Parameters:
  • gamma_bg (float or array_like) – The background photonionization rate in units of 1e-12 s**-1

  • delta (float or array_like) – The underlying overdensity

  • temp (float or array_like) – The kinectic temperature of the gas in 1e4 K

  • redshifts (float or array_like) – Correspoding redshifts along the los
