Description
We revisit the classic system of a Schwarzschild black hole with a thin accretion disk to investigate how to determine the parameters of this system (mass M, inclination angle i, and distance D) from the observation of shadow. A novel point of our analysis is to leave the distance between the black hole and observer to be finite. We show that one can determine (M, i, D) from the information of shadow and the flux of disk.
