Source Notes:
Source position and its uncertainty:
From Acero et al. (2010) and Aharonian et al. (2006):
- The centre for the Galactic Diffuse is taken as the location of the Galactic Centre...
- R.A. (J2000): 17h45m39.6s +/- 0.4s(stat) +/- 0.4s(syst)
- Dec. (J2000): -29d 00' 22" +/- 6"(stat) +/- 6"(syst)

Spectral Index:
From Acero et al. (2010):
- 2.29 +/- 0.07(stat) +/- 0.20(syst)

Source Extent:
From Acero et al. (2010):
the emission is not only very clearly extended in longitude l (2 deg), but also signi´Čücantly
extended in latitude b (beyond the angular resolution of H.E.S.S.) with a characteristic
root mean square width of 0.2 deg"
