  In our previous work, high-temperature superconductivity (HTSC) was probed
for the first time by using electrical differential conductance Gdiff(V) =
dI/dV data as obtained from current-voltage V(I) measurements on a hydrogenated
graphitic fiber [1]. While our nonlocal method for finding the superconducting
(SC) gap was recently applied to a conventional SC (Pb [2]), the nonlocal Gdiff
method was first proposed in [1]. Herein, we are bringing forth an update on
the topic.
