HGPS Source Notes:
This is one of the 31 firmly-identified objects among the HGPS sources. Four possible associations are listed in Table A.9. "This is a list of astronomical objects, extracted from catalogs of plausible counterparts, which are are found to be spatially coincident with the HGPS source":
- 3FGL J1356.6−6428 (3FGL)
- G309.8−2.6 (PWN)
- J1357−6429 (PSR)
- 2FHL J1355.1−6420e (2FHL)


Source position and its uncertainty:
From Abramowski et al. (2011):
- R.A. (J2000): 13 56 00 +/- 2'(stat)
- Dec. (J2000): -64 30 00 +/- 2'(stat)

Source Extent:
From Abramowski et al. (2011):
- radius: 0.20 +/- 0.02 deg

Spectral Properties:
From Abramowski et al. (2011):
- Spectral index: 2.2 +/- 0.2(stat) +/- 0.2(syst)
- Normalisation at 1Tev: (2.7 +/- 0.9(stat) +/- 0.4(syst)) e-12 cm-2 s-2 TeV-1

Source Association:
From Acero et al. (2013):
- Analysis of the LAT data from this source leads to its
classification as a clearly identified PWN
From Renaud et al. (2008):
- This PWN is proposed to be associated with PSR J1357-6429.
From Abramowski et al. (2011):
- most likely associated with the young and energetic pulsar PSR J1357-6429,
which is located at a projected distance of ~5pc from the centroid of the VHE emission.
