The EG1-DVCS experiment with CLAS at Jefferson Lab collected semi-inclusive pion electro-production data on longitudinally polarized solid state NH₃ and ND₃ targets with longitudinally polarized electrons of approximately 6 GeV energy. Data on all three pion channels, π +, π– and π⁰, were collected simultaneously. The charged pions were identified by their time-of-flight information whereas the neutral pions were reconstructed from the invariant mass of two photons. The experiment covered a wide kinematic range: 1 GeV ² ≤ Q² ≤ 3.2 GeV², 0.12 ≤ xB ≤ 0.48, 0.0 GeV ≤ P_{h⊥ …}
