py21cmmc.core.CoreForest.tau_GP#
- 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
