Effects of He Rates on the P(k)

Using the Hydrogen best fit parameters:

$$\beta_{\mathrm{H}} = 0.78$$ $$\Delta z_{\mathrm{H}} = 0.04$$

Effects of changing $\beta_{\mathrm{He}}$:

Using Fixed best fit $\Delta z_{\mathrm{He}} = 0.28$

Effects of changing $\Delta z_{\mathrm{He}}$:

Using Fixed best fit $\beta_{\mathrm{He}} = 0.44$
