Query: Constraining the Kerr parameters via X-ray reflection spectroscopy   In a recent paper [Ghasemi-Nodehi & Bambi, EPJC 76 (2016) 290], we have
proposed a new parametrization for testing the Kerr nature of astrophysical
black hole candidates. In the present work, we study the possibility of
constraining the "Kerr parameters" of our proposal using X-ray reflection
spectroscopy, the so-called iron line method. We simulate observations with the
LAD instrument on board of the future eXTP mission assuming an exposure time of
200~ks. We fit the simulated data to see if the Kerr parameters can be
constrained. If we have the correct astrophysical model, 200~ks observations
with LAD/eXTP can constrain all the Kerr parameters with the exception of
$b_{11}$, whose impact on the iron line profile is extremely weak and its
measurement looks very challenging.
