Hierarchical Adaptive Tiling Scheme Catalog

HATS

Hierarchical Adaptive Tiling Scheme

A HATS catalog is a partitioning of objects on a sphere. Its purpose is for storing data from large astronomy surveys, but could probably be used for other use cases where you have large data with some spherical properties.

Check out our ReadTheDocs site for more information on partitioning, installation, and contributing.

See related projects:

• HATS Import (on GitHub) (on ReadTheDocs)
• LSDB (on GitHub) (on ReadTheDocs)

Contributing

See the contribution guide for completed installation instructions and contribution best practices.
