Source Notes:
Source Discovery:
- This detection was announced in July 2012 at the
Gamma 2012 meeting in
Heidelberg by Wouters (poster).
Source position and its uncertainty:
Updated on 130925 from the
NED position to the HESS position
From
H.E.S.S. Collaboration (2013):
- R.A. (J2000): 03 03 23.49 +/- 1.19s(stat) +/- 1.30(syst)
- Dec. (J2000): -24 07 35.86 +/- 15.35"(stat) +/- 19.50"(syst)
Distance:
From
Pita et al. (2013):
- z = 0.2657 +/- 8.6e-05
From
Pita et al.(2012):
- "The best determination of its redshift (
Falomo et al. (2000)) was
based on the plausible identification of a single weak emission line
with [OIII] 5007 Ã…. We confirm this result and propose a more pre-
cise determination of the redshift at z=0.266, given the clear
detection of the emission lines [OII] 3727.3 Ã… in the UVB arm and
[OIII] 5007 Ã… in the VIS arm."
Spectral Properties
From
H.E.S.S. Collaboration (2013):
- Photon index: 4.6 +/- 0.7(stat) +/- 0.2(syst)
Flux:
From
H.E.S.S. Collaboration (2013):
- 1.4% of the Crab Nebula flux above 200 GeV
Variability:
From
H.E.S.S. Collaboration (2013):
- "A hint of variability at the 2.5 sigma level is found."
