Fitted UVB rates to BOSS

Below are the posterior distribution of the parameters for the fit:

From my fit to the BOSS P(k) and tau_HeII the values for the best fit parameters are (brackets show the 95% HPD interval):

$$\beta_{\mathrm{He}} = 0.46 \,\,\, [ \, 0.37 \,\, 0.69 \, ]$$ $$\beta_{\mathrm{H}} = 0.78 \,\,\, [ \, 0.76 \,\, 0.79 \, ]$$ $$\Delta z_{\mathrm{He}} = 0.28 \,\,\, [ \, 0.15 \,\, 0.35 \,]$$ $$\Delta z_{\mathrm{H}} = 0.04 \,\,\, [ \, -0.01 \,\, 0.08 \, ]$$

Links to the text files containing the marginalized Photoheating and Photoionization rates are below:

In each file the columns correspond to:

• 0: Redshift
• 1: HI Photoheating Rate
• 2: HeI Photoheating Rate
• 3: HeII Photoheating Rate
• 4: HI Photoionization Rate
• 5: HeI Photoionization Rate
• 6: HeII Photoionization Rate
