Galaxy Descriptions (HATS)

Original dataset: Nolan Koblischke's astronolan/galaxy-descriptions

This is the same dataset, repartitioned into the spatially indexed HATS format. The scientific content is unchanged.

This catalog contains the original 275,613 galaxy rows, including images, captions, summaries, text embeddings, AION image embeddings, coordinates, survey names, and object identifiers. Conversion added the HATS _healpix_29 spatial index and organized the rows into HEALPix-partitioned Parquet files. A default 10-arcsecond margin catalog is included for spatial crossmatching.

Access with LSDB

import lsdb

catalog = lsdb.open_catalog("hf://datasets/Smith42/galaxy_descriptions_hats")
