<p>The predicted density counts in this format: MODEL_lrg_REGION_MAPS.hp256.fits<br>MODEL is either dnnp (non-linear) or linp (linear)<br>REGION is either desi (full dr9), desic (desi + dec cuts), desicf (desi + dec + pixel completeness cuts) or desicl (desi + dec + imaging condition cuts)<br>MAPS is either known (two maps), known1 (three maps), all (eight maps), allp (nine maps), allpext (eleven maps). The paper fiducial analysis uses `dnnp_lrg_desic_allp.hp256.fits`.</p>
<p>The imaging systematic weights are the inverse of the predicted density counts, normalized such that the total number counts of galaxies multiplied by the weight is the same, e.g., Sum_i Ngal_i x Weight_i = Sum_i Ngal_i where Ngal_i is the number of galaxies in pixel i. </p>

DESI 2024 III: baryon acoustic oscillations from galaxies and quasars
No full textThe DESI collaboration: A.G. Adame et al. -- Dark energy spectroscopic instrument (DESI) survey year 1 results.We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique galaxy and quasar redshifts in the range 0.1 < z < 2.1. Divided by tracer type, we utilize 300,017 galaxies from the magnitude-limited Bright Galaxy Survey with 0.1 < z < 0.4, 2,138,600 Luminous Red Galaxies with 0.4 < z < 1.1, 2,432,022 Emission Line Galaxies with 0.8 < z < 1.6, and 856,652 quasars with 0.8 < z < 2.1, over a ∼ 7,500 square degree footprint. The analysis was blinded at the catalog-level to avoid confirmation bias. All fiducial choices of the BAO fitting and reconstruction methodology, as well as the size of the systematic errors, were determined on the basis of the tests with mock catalogs and the blinded data catalogs. We present several improvements to the BAO analysis pipeline, including enhancing the BAO fitting and reconstruction methods in a more physically-motivated direction, and also present results using combinations of tracers. We employ a unified BAO analysis method across all tracers. We present a re-analysis of SDSS BOSS and eBOSS results applying the improved DESI methodology and find scatter consistent with the level of the quoted SDSS theoretical systematic uncertainties. With the total effective survey volume of ∼ 18 Gpc3, the combined precision of the BAO measurements across the six different redshift bins is ∼0.52%, marking a 1.2-fold improvement over the previous state-of-the-art results using only first-year data. We detect the BAO in all of these six redshift bins. The highest significance of BAO detection is 9.1σ at the effective redshift of 0.93, with a constraint of 0.86% placed on the BAO scale. We find that our observed BAO scales are systematically larger than the prediction of thePlanck 2018-ΛCDM at z < 0.8. We translate the results into transverse comoving distance and radial Hubble distance measurements, which are used to constrain cosmological models in our companion paper.This material is based upon work supported by the U.S. Department of Energy (DOE), Office of Science, Office of High-Energy Physics, under Contract No. DE-AC02-05CH11231, and by the National Energy Research Scientific Computing Center, a DOE Office of Science User Facility under the same contract.
