In the context of the S-PLUS Fornax Project (S+FP), we performed a statistical characterization of the galaxy population of the Fornax cluster (D ≈ 20 Mpc) in the 12 optical bands of the survey over a total area of about 45 square degrees. Using the S-PLUS photometric catalogs we carry out a principal component analysis (PCA) on the structural and photometric parameters of two spectroscopic galaxy samples, and a clustering analysis to obtain the natural distribution of the samples on their principal components. The samples correspond to Fornax confirmed members and confirmed background galaxies. Our main goal is to apply the results of that analysis to a third sample of candidate galaxies with no radial velocities in order to identify new Fornax members not catalogued before.
