Fig. 2.

Heating functions caused by decaying magnetic turbulence (solid lines) and ambipolar diffusion (dashed lines) in PMFs models with different B₀ (left) and n_B (right). The inset panel shows $Γ_{pmf}^{(dt)} (z, B_{0}, n_{B}) / Γ_{pmf}^{(dt)} (z, B_{0}, n_{B} = - 2.9)$ $\Gamma_{\mathrm{pmf}}^{\mathrm{(dt)}}(z,B_0,n_{\mathrm{B}})/\Gamma_{\mathrm{pmf}}^{\mathrm{(dt)}}(z,B_0,n_{\mathrm{B}}=-2.9)$ for the purpose of distinguishing lines in the 21 cm line formation region.
