Query: A study for testing the Kerr metric with AGN iron line eclipses   Recently, two of us have studied iron line reverberation mapping to test
black hole candidates, showing that the time information in reverberation
mapping can better constrain the Kerr metric than the time-integrated approach.
Motivated by this finding, here we explore the constraining power of another
time-dependent measurement: an AGN iron line eclipse. An obscuring cloud passes
between the AGN and the distant observer, covering different parts of the
accretion disk at different times. Similar to the reverberation measurement, an
eclipse might help to better identify the relativistic effects affecting the
X-ray photons. However, this is not what we find. In our study, we employ the
Johannsen-Psaltis parametrisation, but we argue that our conclusions hold in a
large class of non-Kerr metrics. We explain our results pointing out an
important difference between reverberation and eclipse measurements.
