We introduce scattering covariances on the sphere in [Mousset et al. (2024)](https://arxiv.org/abs/xxxx.xxxxx), which extend to spherical settings similar scattering transforms introduced for 1D signals by [Morel et al. (2023)](https://arxiv.org/abs/2204.10177) and for planar 2D signals by [Cheng et al. (2023)](https://arxiv.org/abs/2306.17210).
