Linear Lagrangian bias parameter b_1L for the haloes, measured for different boxsizes L and comparing simulation and model. The model agrees well with the simulation at the L = 50 h⁻¹ Mpc scale, but both are inconsistent with the true large-scale bias relation from Lazeyras et al. (2016) due to effects from the limited size of the simulation volume. Evaluation on larger boxes moves the prediction closer to the known relation, but some deviation is maintained.
