  \caption{Spectral parameters for the radial bins surrounding
  PSR~J1826--1334. \emph{PSF} denotes a HESS\ point-source
  analysis at the pulsar position. The background estimate for the
  numbers in the table have been derived from reflected positions
  within the same field of view. The energy flux and surface
  brightness are given for the energy range between 0.25 and 10~TeV.
