# Galaxies for training astroPT
Here we have ~8.5 million galaxy cutouts from the [DESI legacy survey DR8](https://www.legacysurvey.org/dr8/description/).
The cut outs are 512x512 pixel jpg images centred on the galaxy source.
There is also accompanying metadata!
The metadata is in parquet format in the root dir of this repo.
You can link the metadata with the galaxies via their dr8_id.
