Slices of 25 Mpc h⁻¹ thick though different density fields involved in the calibration of the BAM products and its products. The bottom panel shows the reconstruction of the halo number density field using different models of halo bias (see Sect. 2.6). The rightmost column shows the galaxy density field from the reference and from BAM, built by populating halo catalogues with a model of halo occupation distribution (see Sect. 4).
