Note also that the harmonic-coordinates 3PN equations of motion [69*, 71*] depend, in addition to , on two
arbitrary constants and parametrizing some logarithmic terms. These constants are closely related to the
constants and in the partie-finie integral (162); see Ref. [71*] and Eq. (185) below for the precise
definition. However, and are not “physical” in the sense that they can be removed by a coordinate
transformation.
