DESI EDR (SV3) spectra — L1 (release v1) This L1 repository contains 1,060,507 spectra matched across the release, in 21 shards (about 80 GB). Schema spectrum struct per row: lambda (vacuum, barycentric, observer frame, Å; fixed 7,781-sample grid), flux (×10⁻¹⁷ erg s⁻¹ cm⁻² Å⁻¹), ivar, lsf_sigma (approximate line-spread σ per pixel), mask (native; nonzero = bad — verified), valid (mask==0 AND ivar>0 AND finite(flux)). Plus object_id (TARGETID), ra, dec, and source… See the full description on the dataset page: https://huggingface.co/datasets/kshitijd/mmu-norm-desi.
