  In an age of large astronomical dateset and severe cosmological tensions, the
case for model independent analyses is compelling. We present a set of 14
baryon acoustic oscillations measurements in thin redshift shells with 3%
precision that were obtained by analyzing BOSS DR12 and eBOSS DR16 galaxies in
the redshift range $0.32<z<0.66$. Thanks to the use of thin shells, the
analysis is carried out using just redshifts and angles so that the fiducial
model is only introduced when considering the mock catalogs, necessary for the
covariance matrix estimation and the pipeline validation. We compare our
measurements, with and without supernova data, to the corresponding constraints
from Planck 2018, finding good compatibility. A Monte Python module for this
likelihood is available at https://github.com/ranier137/angularBAO .
