Source Notes:

Source position and its uncertainty:
From Aharonian et al. (2005):
- RA (J2000): 13 02 49.3 +/- 2.3s(stat)
- Dec (J2000): -63 49 53 +/- 17"(stat)
- systematic error on pointing is 20"

Spectral Properties:
From Abramowski et al. (2013):
- 2010 Data - Spectral index: 2.92 +/- 0.30(stat) +/- 0.20(sys)
- 2004 Data - Spectral index: 2.81 +/- 0.10(stat) +/- 0.20(sys)
From Aharonian et al. (2005):
- 2004 Data - Spectral index: 2.7 +/- 0.2(stat) +/- 0.2(sys)

Emission Characteristics:
From Sushch et al. (2013):
- "These new observations partially overlap with the beginning of a
spectacular gamma-ray flare reported by the Fermi-LAT (here too). The
H.E.S.S. observations show both flux and spectral properties similar
to those reported in previous periastron passages, without any
signature of the emission enhancement seen at GeV energies. A careful
statistical study based on the Fermi and H.E.S.S. lightcurves leads to
the conclusion that the GeV and TeV emission during the flare have a
different physical origin."
