Source Notes:
Source position and its uncertainty:
From
Abdo et al. (2009):
- R.A. (J2000): 22h 28m 44s
- Dec. (J2000): 61d 10m
... statistical position error of 0.165 deg
Source Extent:
From
Abdo et al. (2009):
- "Milagro identifies this source as clearly not a point source,
... with a long extension to the south."
- the extent measured is not given
Source Association:
From
Cao et al. (2021):
- Boomerang Nebula may be associated with
LHAASO J2226+6057
From
Acero et al. (2013):
- This LAT emission from this source below 10 GeV is likely from a
pulsar
From
Acciari et al. (2009):
- This source could be associated with the VERITAS source
G106.3+2.7
From
Abdo et al. (2009):
- report a source associated with 0FGL J2229.0+6114 with a statistical
significance of 6.6sigma.
- This source is extended and is associated with a Fermi pulsar (J2229+6114)
and is therefore postulated to be the PWN of this pulsar
Source Flux:
From
Abdo et al. (2009):
- The flux quoted here is based on a comparison of the flux at 35 TeV
of 70.9e-17 /TeV /s /cm2 with that from the Crab (162.6e-17 /TeV /s /cm2)
also quoted at 35 TeV.
