Testing consistency of $\Omega_b h^2$ in the Planck data

Understand

We find that the cosmic microwave background temperature and polarization power spectra measurements from Planck constrain the parameter $\Omega_bh^2$ mostly through: A) the amplitude of Thomson scattering and B) a factor that ensures Thomson scattering does not violate momentum conservation of the baryon-photon fluid.

This allows us to obtain two distinct but comparably strong constraints on $\Omega_b h^2$ from the Planck data alone.
They are consistent, showing robustness of the Planck $\Omega_b h^2$ constraint.
We can alternatively rephrase these constraints as A) the change of the Thomson scattering cross section since recombination is less than $\sim 2\%$ and B) momentum during recombination is conserved to better than $\sim 2\%$ by Thomson scattering.
