Source Notes:

More details on this source from The Third HAWC Catalog will soon be added to TeVCat.

Source Association:
From Albert et al. (2020):
- From Table 3, "the nearest GeV source in 4FGL (Abdollahi et al. 2020)
and its separation from the 3HWC source; the source class as listed in 4FGL
where available (bcu: active galaxy of uncertain type; PSR: pulsar, identified
by pulsations; unk: unknown); the nearest pulsar and corresponding separation
from the ATNF pulsar catalog (Manchester et al. 2005); and the nearest
SNR, separation distance, and type from the SNRCat (Ferrand & Safi-Harb 2012).":
- 4FGL J1740.5+1005, 0.22 deg, PSR
- J1740+1000, 0.13 deg
- G034.0+20.3, 0.13 deg, filled-centre

A PeVatron:

From Cao et al. (2024):
- This source is listed as being a UHE source in Table 2. This means
that it has a detection above 100 TeV at a significance level
corresponding to a test statistic of greater than 20.
