HGPS Source Notes:
"This is one of the fourteen EXTERN sources in the HGPS catalog, i.e., VHE sources in the HGPS region previously detected by H.E.S.S. that were not reanalyzed in the paper:"
- "Given the difficulties with modeling complex source morphologies, we decided to restrict the HGPS analyses to a symmetrical Gaussian model assumption and exclude all firmly identified shell-like sources and the very complex GC region from reanalysis."

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":
- 2FHL J1713.5−3945e (2FHL)
- 3FGL J1713.5−3945e (3FGL)
- G347.3−0.5 (SNR)
- 2FHL J1714.1−4012 (2FHL)
