MMU 20M positional crossmatch spine

This release contains 20,415,199 unique DESI DR1 TARGETID anchors and recomputed positional associations to Multimodal Universe HATS catalogs. It is a reproducible positional crossmatch product, not a claim that every association is a certain physical identity.

Recommended views

spine/ — every anchor with positional and conservative secure modality flags.
spine_positional_multimodal/ — 4,184,585 anchors with at least one positional association in addition to DESI redshift.
spine_secure_multimodal/ — 3,927,193 anchors with at least one conservative secure association.
links/<catalog>/candidates/ — HATS association table containing up to 10 nearest candidates inside the catalog-specific radius.
links/<catalog>/best/ — nearest candidate plus ambiguity metadata.
links/<catalog>/many_to_one_sources/ — source rows selected by more than one spine object; join this on source_row_id.
links/<catalog>/source/ — thin source catalog (coordinates and identifiers) with the complete conservative margin used by the crossmatch.

If a source catalog has no positional matches, its bundle contains EMPTY.json and QA metadata instead of empty HATS association directories.

All HATS collections are spatially partitioned Parquet and include conservative order-based margins at least as wide as 3 arcsec (or the catalog-specific match radius). Open them directly:

import lsdb

spine = lsdb.open_catalog(
    "hf://datasets/kshitijd/mmu-xmatch-20m/spine_secure_multimodal",
    columns=["spine_id", "ra", "dec", "Z", "n_mod", "n_secure_mod"],
)
sdss_best = lsdb.read_hats(
    "hf://datasets/kshitijd/mmu-xmatch-20m/links/sdss_sdss/best"
)

Match-quality fields

_dist_arcsec: angular separation.
candidate_rank: increasing separation, with 1 used by the best view.
n_candidates: candidates retained within the radius.
ambiguous: more than one candidate is inside the radius.
candidate_limit_reached: 10 candidates were returned; additional neighbors may exist and the association should not be treated as secure.
source_row_id: stable row key in the included thin source catalog.
native_source_id: upstream identifier when the source catalog supplies one.
secure_<group>: a unique candidate whose source row is not selected by another spine object and whose candidate limit was not reached.

Method and limitations

Each source catalog was projected to coordinates and identifiers, written to HATS, given a conservative margin at least as wide as its match radius, and crossmatched with LSDB's KD-tree implementation. Boundary completeness is validated by requiring the right-side margin. Distances are validated to remain inside the stated radius. Candidate multiplicity and global many-to-one reuse are published rather than silently forcing every association to be one-to-one.

These are positional associations. The pipeline does not propagate proper motions between survey epochs, model morphology or blended sources, or calculate Bayesian counterpart probabilities. Users studying crowded fields, high-proper- motion sources, or high-energy catalogs should apply domain-specific quality criteria. Full provenance, software versions, counts and validation results are in manifest.json.

Aggregate metadata follows the upstream Multimodal Universe release, but licenses and acknowledgement requirements of each source subset still apply. Consult the upstream dataset card before redistribution or publication.
