Galaxy Benchmark
================

Compiled galaxy measurements for the BGS summary statistics pipeline benchmark.
Each entry records the cosmological convention, sample selection, and — where
available — tabulated data in a standard FITS schema for direct comparison with
pipeline outputs.

**Selection criteria:** publications since 2000; citation count > 100 on NASA
ADS (recent DESI, Euclid, and JWST papers excepted); data publicly available
(VizieR, journal supplement, GitHub, or Zenodo).
