Object-level positional crossmatch built strictly from the
MultimodalUniverse v1.5 HATS catalogs
with LSDB. Anchor: the DESI DR1 redshift catalog
(LSDB/desi-dr1-zcat), filtered to primary rows with clean redshifts
(ZCAT_PRIMARY & ZWARN==0); every object therefore starts with a measured
redshift, and DESI spectra payloads are attached where the EDR release
provides them.
