Note also that the harmonic-coordinates 3PN equations of motion as they have been obtained in Refs. [37Jump To The Next Citation Point, 38Jump To The Next Citation Point] depend, in addition to c, on two arbitrary constants ' r1 and ' r2 parametrizing some logarithmic terms. These constants are closely related to the constants s1 and s2 in the partie-finie integral (124View Equation); see Ref. [38Jump To The Next Citation Point] for the precise definition. However, ' r1 and ' r2 are not “physical” in the sense that they can be removed by a coordinate transformation.
