报告提纲

• We present constraints on deformation parameter α₁₃, α₂₂ and ε₃ using flux-resolved spectroscopy of simultaneous 2013 Xmm-Newton and NuSTAR observations of MCG-06-30-15.

• Source selection for future studies

  ① Prominent iron line

  ② Low mass accretion rate

  ③ High spin(a_*>0.9)

  ④ higher resolution at iron line (future telescopes)

• Systematic Uncertainties.

• Testing gravity for other modified theories.
