# 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](https://ui.adsabs.harvard.edu/abs/2025arXiv250315312E/abstract)). |
|
|
|
|
|
### 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](https://ui.adsabs.harvard.edu/abs/2024A%26A...691A.308S/abstract) and [Siudek et al. 2025b](https://ui.adsabs.harvard.edu/abs/2025A%26A...700A.209S/abstract). |
|
|
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 |
|
|
|
|
|
### DESI Sample Selection |
|
|
Applied quality cuts to DESI EDR: |
|
|
- `ZCAT_PRIMARY == True` |
|
|
- `ZWARN == 0` or `ZWARN == 4` |
|
|
- `COADD_FIBERSTATUS == 0` |
|
|
- `SPECTYPE != 'STAR'` |
|
|
- `Z > 0` |
|
|
|
|
|
### Euclid Sample Selection |
|
|
From Euclid Consortium: Siudek et al. 2025 ([arXiv:2503.15312](https://ui.adsabs.harvard.edu/abs/2025arXiv250315312E/abstract)). |
|
|
|
|
|
