Query: Reply to "Comment on 'Can accretion disk properties observationally
  distinguish black holes from naked singularities?'"   In the Comment on "Can accretion disk properties observationally distinguish
black holes from naked singularities?", by Bertrand Chauvineau, Phys. Rev. D
{\bf 98}, 088501 (2018), the author did show that the metric used in Z.
Kov\'{a}cs and T. Harko, Phys. Rev. D {\bf 82}, 124047 (2010), and initially
introduced in K. D. Krori and D. R. Bhattacharjee, J. Math. Phys. \textbf{23},
637 (1982) and K. K. Nandi, P. M. Alsing, J. C. Evans, and T. B. Nayak, Phys.
Rev. D \textbf{63}, 084027 (2001), does not satisfy the Einstein gravitational
field equations with a minimally coupled scalar field. In our reply we would
like to point out that this result is actually not new, but it was already
published in the literature. Moreover, a rotating solution that generalizes the
Kerr metric for a nonminimally coupled scalar field does exist. We briefly
discuss the nature of the singularities for the generalized metric, and point
out that it can be used as a testing ground to differentiate black holes from
naked singularities. We also mention the existence of some other typing or
technical errors existing in the literature.
