mmu_sdss_sdss
mmu_sdss_sdss HATS Catalog Collection
This is the collection of HATS catalogs representing mmu_sdss_sdss.
This dataset is part of the Multimodal Universe,
a large-scale collection of multimodal astronomical data. For full details, see the paper:
The Multimodal Universe: Enabling Large-Scale Machine Learning with 100TBs of Astronomical Scientific Data.
Access the catalog
We recommend the use of the LSDB Python framework to access HATS catalogs.
LSDB can be… See the full description on the dataset page: https://huggingface.co/datasets/UniverseTBD/mmu_sdss_sdss.sdss---

SDSS spectra — L1 (release v1)
This L1 repository contains 271,966 spectra matched across the release, in 11 shards (about 15 GB).
Schema
spectrum struct per row: lambda (vacuum, heliocentric, observer frame, Å; variable length ≤ ~4,700), flux (×10⁻¹⁷ erg s⁻¹ cm⁻² Å⁻¹), ivar, lsf_sigma, mask (native; nonzero = bad — verified), valid. Plus object_id, positions, metadata.
Padding: the upstream arrays used lambda = −1 with zero inverse variance for padding. Those… See the full description on the dataset page: https://huggingface.co/datasets/kshitijd/mmu-norm-sdss.mmu_sdss_sdss---

sdss-asteroid-taxonomy
SDSS-based Asteroid Taxonomy
Part of the Orbital Mechanics Datasets collection on Hugging Face.
Compositional taxonomy for 107,466 SDSS photometric observations of 63,468
asteroids, classified using the scheme of Carvano et al. (2010). Each observation includes
SDSS u'g'r'i'z' log-reflectances, a taxonomic class assignment, and a probability score.
Orbital elements from the asteroid catalog are merged in for asteroids with known orbits.

sdss-nsa-metasdss_dr17_spectra_for_classification
SDSS DR17 Spectral Classification Parquet Benchmark
This fixed supervised benchmark classifies SDSS DR17 optical spectra as GALAXY, QSO, or STAR. Rows contain native FITS arrays, common-grid spectral inputs, identifiers, derived spectral-quality fields, and metadata matched from specObj-dr17.fits.
