# Galaxy metadata for pairing with `smith42/galaxies' dataset
Here we have metadata for ~8.5 million galaxies.
This metadata can be paired with galaxy jpg cutouts from the [DESI legacy survey DR8](https://www.legacysurvey.org/dr8/description/),
the cut outs are found here: [https://huggingface.co/datasets/Smith42/galaxies](https://huggingface.co/datasets/Smith42/galaxies).
I've split away 1% of the metadata into a test set, and 1% into a validation set.
The remaining 98% of the metadata comprise the training set.
