Using the Helium best fit parameters:

\[\beta_{\mathrm{He}} = 0.46\] \[\Delta z_{\mathrm{He}} = 0.28\]

Effects of changing \(\beta_{\mathrm{H}}\):

Using Fixed best fit \(\Delta z_{\mathrm{H}} = 0.04\)

Effects of changing \(\Delta z_{\mathrm{H}}\):

Using Fixed best fit \(\beta_{\mathrm{H}} = 0.78\)
