Significance map of the H.E.S.S. dataset towards HESS J1825–137 in the various energy bins of interest. An over-sampling radius of 0.1° is used. The white circles show the mask applied to the emission microquasar LS 5039 and the gamma-ray source HESS J1826–130. The turquoise dot indicates the position of the pulsar, PSR B 1823–13. There is a clear change in the size of the emission in the different bins.
