The standard model predictions for W γ and Z γ production are tested using an integrated luminosity of 200 pb-1 of pp̅ collision data collected at the Collider Detector at Fermilab. The cross sections are measured by selecting leptonic decays of the W and Z bosons, and photons with transverse energy ET>7 GeV that are well separated from leptons. The production cross sections and kinematic distributions for the W γ and Zγ data are compared to SM predictions.
