Based on the VIMOS Public Extragalactic Redshift Survey (VIPERS, z>0.5) and on the GALEX-SDSS-WISE Legacy Catalog (GSWLC, z<0.3), we constrained a set of Star Formation Rate (SFR) calibrators able to work from z=0 to z=0.9. Such calibrations are crucial to study the formation and evolution of galaxies over cosmic time. We used as estimators photometric bands from ultraviolet (UV) to mid-infrared (mid-IR) and the spectral lines Hβ, [OII]λ3727 and [OIII]λ5007. Because the Hα spectral line is shifted out of the optical window above z∼0.5, we assume a reference SFR obtained from the spectral energy distribution reconstructed with CIGALE.
