Shot noise and reconstruction of the acoustic peak

Understand

We study the effect of noise in the density field, such as would arise from a finite number density of tracers, on reconstruction of the acoustic peak within the context of Lagrangian perturbation theory.

Reconstruction performs better when the density field is determined from denser tracers, but the gains saturate at n~1e-4(h/Mpc)^3.
For low density tracers it is best to use a large smoothing scale to define the shifts, but the optimum is very broad.
