Notes. From left to right: mean and standard deviation, median and interquartile range of the absolute value of the torsion in kpc−1, and finally the fit’s χ2 per number of degrees of freedom. It is worth recalling, from Sect. 3.4, that we expected that values above 0.1 × 10−2 kpc−1 may signal a nonspherical DM distribution, as the effect of the aspherical galactic plane is not strong enough.
