Legacy Survey Dataset
Description
This dataset contains astronomical observations from the Legacy Survey.
Features
- image: Multi-band astronomical imaging data with flux, mask, inverse variance, PSF FWHM, and scale information
- blobmodel: Model image of detected sources
- rgb: RGB composite image
- object_mask: Segmentation mask for objects
- catalog: Catalog of detected objects with photometric and shape measurements
- EBV: Galactic extinction E(B-V)
- FLUX_G/R/I/Z: Flux measurements in g, r, i, z bands
- FLUX_W1/W2/W3/W4: WISE flux measurements
- SHAPE_R/E1/E2: Shape parameters (half-light radius, ellipticity components)
- object_id: Unique object identifier
- ra/dec: Right ascension and declination coordinates
Usage
from datasets import load_dataset
ds = load_dataset("your-username/legacy-survey")
# Access an RGB image directly as PIL
rgb_image = ds["train"][0]["rgb"]
# Access coordinates
ra, dec = ds["train"][0]["ra"], ds["train"][0]["dec"]
