    <subfield code="a">&lt;p&gt;We present a morphological classification of J-PLUS EDR sources into compact (i.e. stars) and extended (i.e. galaxies). Such classification is based on the Bayesian modelling of the concentration distribution, including observational errors and magnitude + sky position priors. We provide the star / galaxy probability of each source computed from the gri images. The comparison with the SDSS number counts support our classification up to r ~ 21. The 31.7 deg² analised comprises 150k stars and 101k galaxies.&lt;/p&gt;</subfield>
