Source Notes:
Announced at the 2011 ICRC. 5.1 sigma detection in 60 hrs; hard spectrum.
Source position and its uncertainty:
On 20160405 the source position was updated from that provided by
NED to that given in
Abeysekara et al. (2016)
From
Abeysekara et al. (2016):
- R.A. (J2000): 17 44 01.2 +/- 2.4s(stat)
- Dec. (J2000): +19 32 47 +/- 47"(stat)
- A systematic error of 25" is also present
Flux:
From
Abeysekara et al. (2016):
- the integral flux above 180 GeV is approximately 1.6% that of the
Crab Nebula
Spectral Properties:
From
Ahnen et al. (2017):
- spectral index: 2.4 +/- 0.2(stat) +/- 0.2(syst)
From
Abeysekara et al. (2016):
- Spectral index: 2.7 +/- 0.7(stat) +/- 0.2(syst)
Distance:
From
Heidt et al. (1999):
- redshift is z = 0.084 +/- 0.001
