  We argued previously that the well-known equation for hydrostatic equilibrium
in a static spherically symmetric spacetime supported by an isotropic perfect
fluid should be called the Oppenheimer-Volkoff (OV) equation, rather than the
Tolman-Oppenheimer-Volkoff (TOV) equation, a later ArXiv manuscript has
disagreed. Here we reply to that comment, reaffirming the original argument.
