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. ## Useful links Paper here: [https://arxiv.org/abs/2405.14930](https://arxiv.org/abs/2405.14930) Models here: [https://huggingface.co/Smith42/astroPT](https://huggingface.co/Smith42/astroPT) Code here: [https://github.com/smith42/astroPT](https://github.com/smith42/astroPT) Upstream catalogue is [on Zenodo](https://zenodo.org/records/8360385) and paper describing the catalogue is available as [Walmsley+2023](https://doi.org/10.1093/mnras/stad2919).
