Notes. An exponentially cut-off power law was used for the spectral component. TS is the Test Statistic and Nsrc is the number of source events attributed to the source. RA is the Right Ascension and Dec the Declination of the fitted source model (J2000). For the disk model, r is the radial extension of the disk, for the Gaussian model, r is the Gaussian σ, and for the shell model, r is the inner radius and w is the shell width. k0 is given in units of 10−11 ph cm−2 s−1 TeV−1 and Ec in units of TeV.
Values are from the H.E.S.S. Collaboration (2018b). “n.c.” signals that the information was not communicated in the publication.
