We also find that the CNN redshifts are unbiased with respect to galaxy inclination, and that $\sigma_{MAD}$ decreases with the signal-to-noise ratio (SNR), achieving values below 0. 007 for SNR >100, as in the deep stacked region of Stripe 82.

A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1. 2.
