Notes. “Spec-z” and “photo-z” mean galaxy surveys with spectroscopic or photometric redshift data, respectively. “DES” stands for Dark Energy Survey.
A p-value of 0.002 is quoted in the original paper, which we convert to S/N by using Eq. (C.3).
The differences between Sugiyama et al. (2018) and Li et al. (2018) are that the former used a Fourier-space analysis and a density-weighted pairwise estimator, while the latter used a real-space analysis and a uniform-weighting pairwise momentum estimator.
Galaxy peculiar velocities form SDSS/DR7 in Planck Collaboration Int. XXXVII (2016) and BOSS/DR10 in Schaan et al. (2016) are obtained by reconstructing the linear peculiar velocity field from the density field.
