Ratios between the power spectrum of the PineTree mocks and the validation catalogues for different mass bins and at voxel resolutions. For the subplots shown from left to right, the voxel size is decreasing according to the Table 1 and also indicated by the annotations in the top row. From top to bottom, each row shows the ratio for increasing mass bins. As with all previous figures, the quantities shown here were all computed using an ensemble of 30 fields.
