Listed in Hugging Face Datasets
Galaxies for training astroPT Here we have ~8.5 million galaxy cutouts from the DESI legacy survey DR8.
Description
The cut outs are 512x512 pixel jpg images centred on the galaxy source. I've split away 1% of the images into a test set, and 1% into a validation set.
The remaining 98% of the images comprise the training set. Metadata (galaxy properties) There is also accompanying metadata! To combine the metadata with the galaxy images you can do (for example): from datasets import… See the full description on the dataset page: huggingface.co/datasets/Smith42/galaxies.
