We describe the observations and redshift measurement for the 269 243 observed ELG spectra, and then present the large-scale structure catalogues, used for the cosmological analysis, and made of 173 736 reliable spectroscopic redshifts between 0.6 and 1.1. We perform a spherically averaged baryon acoustic oscillations (BAO) measurement in configuration space, with density field reconstruction: the data two-point correlation function shows a feature consistent with that of the BAO, the BAO model being only weakly preferred over a model without BAO (Delta chi(2) < 1). Fitting a model constrained to have a BAO feature provides a 3.2 per cent measurement of the spherically averaged BAO distance D-V(z(eff))/r(drag) = 18.23 +/- 0.58 at the effective redshift z(eff) = 0.845.Astronomy & Astrophysicsgalaxies: distances and redshiftsdark energydistance scalelarge-scale structure of universecosmology: observationsdark energy surveydigital sky surveypower-spectrum analysisstar-formation historyacoustic-oscillationsdistance measurementsquasar samplemodelreconstructionsystematicsThe completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: large-scale structure catalogues and measurement of the isotropic BAO between redshift 0.6 and 1.1 for the Emission Line Galaxytext::journal::journal article::research article
