Query: On the energetics of a possible relativistic jet associated with the
  binary neutron star merger candidate S190425z   Advanced LIGO and Virgo detectors reported the first binary neutron star
merger candidate in the third observing run, S190425z, on 25th April 2019. A
weak $\gamma$-ray excess was reported nearly coincidentally by the INTEGRAL
satellite which accidentally covered the entire localization region of
AdvLIGO/VIRGO. Electromagnetic follow-up in longer wavelengths has not lead to
the detection of any associated counterparts. Here we combine the available
information from gravitational-wave measurements and upper limits of fluence
from \textit{INTEGRAL} to show that the observations are completely consistent
with a relativistic Gaussian structured jet and a typical short duration
Gamma-Ray Burst (GRB) being produced in the merger. We obtain posterior bounds
on the on-axis isotropic equivalent energy of the associated GRB under
different prior distributions. This study demonstrates that even limited GW and
EM information could be combined to produce valuable insights about outflows
from mergers. Future follow-ups may help constrain the jet structure further,
especially if there is an orphan afterglow detection associated with the
candidate.
