In this Github, we save the Gaia eDR3 source IDs of the Nyx stream stars that pass the strongest cuts, with the neural network cut S > 0.95, and a probability to belong to the Gaussian distribution of the Nyx stream higher than 95%. These stars are discussed in details in the paper above.

This paper by Bryan Ostdiek et al. built the neural network and applied it to Gaia DR2, to build an accreted stellar catalog that can be found here.

This paper by Lina Necib et al. analyzes the different structures in the accreted catalog.
