Search for γ-ray line signals from dark matter annihilations in the inner Galactic halo from 10 years of observations with H.E.S.S.

See Supplemental Material at http://link.aps.org/ supplemental/10.1103/PhysRevLett.120.201101 for more details on the observational data set at the Galactic center, the signal and background measurement technique, the expected limit computation together and a study of the systematic uncertainties. In addition, the dependency of the limits for different dark matter profiles is provided.
