Table 1: Fit results for different spectral models for the whole emission region within an integration radius of 0.8 $^\circ$ around the best fit position and the background derived from off-data. The differential flux normalisation I₀ is given in units of $10^{-12} ~ {\rm cm}^{-2} ~ {\rm s}^{-1} ~ {\rm TeV}^{-1}$ . E, $E_{{\rm B}}$ , and $E_{{\rm c}}$ are given in units of TeV. The last column gives the integrated flux above the spectral analysis threshold of 270 GeV in units of $10^{-11}~ {\rm cm}^{-2} ~ {\rm s}^{-1}$ . The power-law fit provides a rather poor description of the data. Thus fits of a power law with an exponential cutoff (row 2), a power law with an energy dependent photon index (row 3), and a broken power law (row 4; in the formula, the parameter S = 0.1 describes the sharpness of the transition from $\Gamma _1$ to $\Gamma _2$ and is fixed in the fit) are also given. Note that some of the fit parameters are highly correlated.
Table 2: Spectral parameters for the radial bins surrounding PSR J1826-1334. 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.
