can be seen that the alignment signal shows a clear transition from the 1- to the 2-halo regime; in particular, low mass haloes show indications of a different angular momentum$-$large-scale alignment behaviour in the 2-halo regime, suggesting an important relationship between alignment and halo term. This can be interpreted as different physical mechanisms producing the alignment in the 1- and 2-halo terms.

We make quantitative estimates of the alignments for the 1- and 2-halo terms separately from the cross-correlation functions shown in Figure \[fig:3D\] as well as from the other samples of DM haloes with intermediate masses (for a total of 13 samples of varying halo masses). We only consider pairs that are separated by a distance at least as large as the transition between regimes for the 2-halo term, and at shorter separations for the 1-halo calculations.

In order to avoid effects of covariance between the correlation function bins to some extent, we make global 1- and 2-halo term estimates of the ratios between the correlation functions in the directions perpendicular and parallel to the angular momentum of haloes, using all the halo-particle pairs separated by distances within the 1- and 2-halo ranges (i.e. we do not use the
