### Abstract

Recently we developed a time-domain code to calculate the gravitational self-force on a point particle moving around a Schwarzschild black hole. To know how the force affects the particle's motion, it is useful to estimate the self-force correction of some characteristic variables of the orbits (e.g. ISCO frequency, periastron shift). In this work, we focus on the self-force effect on the periastron shift and investigate how to evaluate the correction from the numerical results of the self-force with our time-domain code.
