Spherinator and HiPSter are tools that provide explorative access and visualization for multimodal data from extremely large astrophysical datasets, ranging from exascale cosmological simulations to multi-billion object observational galaxy surveys.
HiPSter uses a trained model from Spherinator with a spherical latent space to create HiPS tilings and a catalog that can be visualized interactively on the surface of a sphere using Aladin Lite.
pip install git+https://github.com/HITS-AIN/HiPSterThe HiPSter package provides a CLI to create HiPS tilings and a catalog from the spherical latent
space representation.
