AstroPT Euclid Dataset
A large-scale multi-band astronomical imaging and photometric dataset from the Euclid Q1 dataset, designed for training deep learning models for astronomical analysis.
Overview
This dataset contains 331,759 Euclid bright and large galaxies (HE<22.5 & segmentation_area>0) with simultaneous observations in visible and near-infrared bands from the Euclid mission, complemented by optical photometry from ground-based surveys. It is specifically curated… See the full description on the dataset page: https://huggingface.co/datasets/msiudek/astroPT_euclid_dataset.astroPT_euclid_desi_dataset
