Query: VERITAS Detection of LS 5039 and HESS J1825-137   With 8 hours of observations, VERITAS confirms the detection of two very high
energy gamma-ray sources. The gamma-ray binary LS 5039 is detected with a
statistical significance of $8.8\sigma$. The measured flux above 1 TeV is $(2.5
\pm 0.4) \times 10^{-12} \rm \, cm^{-2} \, s^{-1}$ near inferior conjunction
and $(7.8 \pm 2.8) \times 10^{-13} \rm \, cm^{-2} \, s^{-1}$ near superior
conjunction. The pulsar wind nebula HESS J1825-137 is detected with a
statistical significance of $6.7\sigma$ and a measured flux above 1 TeV of
$(3.9 \pm 0.8) \times 10^{-12} \rm \, cm^{-2} \, s^{-1}$.
