I don't understand why do they need this complicated algorithm. If there is such a blatant bias then it can be detected by sampling a few million random tetrahedra; and that can be done instantaneously. Also, why don't they publish the list of positions of all these galaxies? (Or I couldn't find it easily on either of the original articles [0,1]). If there's just a million of them, this is around the same size as a single high-resolution color image. Then people can download the positions and find the asymmetries themselves!

Here is a notebook for playing with it: https://nbodykit.readthedocs.io/en/latest/cookbook/boss-dr12-data.html https://nbodykit.readthedocs.io/en/latest/cookbook/boss-dr12...
