Erratum: Direct photon production at next-to-next-to-leading order (Physical Review Letters (2017) 118 (222001) DOI: 10.1103/PhysRevLett.118.222001)

Since the original publication [1], a systematic study of the above-cut contribution to the previously presented NNLO cross sections has been performed. This revealed a small bug in the numerical code used to perform the calculation, resulting from small errors in the cancellation of real-emission singularities in subleading partonic channels. In addition, the implementation of the jettiness cut in this erratum has been changed from (Formula Presented).
