Distance-binned HEALPix summary layers derived from REGALADE

Distance-binned HEALPix summary layers derived from the public CDS/VizieR release of REGALADE (J/A+A/706/A284, DOI: 10.1051/0004-6361/202556896). This release provides equatorial, RING-order HEALPix products at NSIDE 128 and 256. For each pixel and distance bin, the files store galaxy counts, summed stellar mass from the published logM column where available, and a mass-coverage fraction. Distance bins are [0,50), [50,100), [100,200), [200,400), [400,800), [800,1200), [1200,1600), and [1600,2000] Mpc. The derivative products were built directly from the official CDS/VizieR distribution of REGALADE. Included rows satisfy finite RAdeg, DEdeg, and Dist values with 0 < Dist <= 2000 Mpc. Validation counts, checksums, provenance, and product metadata are recorded in regalade_healpix_manifest.json.
