The multi-band photometry of the VOICE imaging data, overlapping with 4.9 deg2 of the Chandra Deep Field South (CDFS) area, enables both shape measurement and photometric redshift estimation to be the two essential quantities for weak lensing analysis. The depth of magAB is up to 26.1 (5limiting) in r-band. We estimate the excess surface density (ESD;Σ) based on galaxy- galaxy measurements around galaxies at lower redshift (0.10
