DESI EDR × Euclid AstroPT Q1 Dataset

Dataset Description

This dataset contains the cross-matched catalog between DESI Early Data Release (EDR) and sample of Quick Data Release 1 (Q1) data from Euclid Consortium: Siudek et al. 2025 (arXiv:2503.15312).

Dataset Summary

• Total Sources: 15,263 galaxies
• Cross-match Radius: 0.5 arcsec
• Data Products:
  • Euclid VIS imaging
  • Euclid NISP imaging (Y, J, H bands)
  • DESI spectra with spectroscopic redshifts
  • metadata: catalog of DESI logM and Z values.
    For more details, see Siudek et al. 2024 and Siudek et al. 2025b.
    The metadata catalog is available at https://huggingface.co/datasets/msiudek/astroPT_euclid_metadata (e.g., select entries where DESI_TARGETID is not null).

Source Data

• COADD_FIBERSTATUS == 0
• SPECTYPE != 'STAR'
• Z > 0

Euclid Sample Selection

From Euclid Consortium: Siudek et al. 2025 (arXiv:2503.15312).
