Simulated baryon overdensities, temperatures, line-of-sight peculiar velocity, and transmission along an example skewer through our box for three different temperature-density relations – one pair each for fixed T₀ and fixed γ – to indicate characteristic variations with respect to the two TDR parameters. The line shifts due to the peculiar velocity component (υ_pec,‖) can be easily noticed. Since the rescaling of the temperatures depends on the densities, inhomogeneous differences are seen in the skewer temperatures in the cases with varying γ. The absorption lines are broader where the temperatures are higher and the amount of broadening is also a function of densities being probed through γ.
