Performs the calculation of the shifted correlator C_shift(t) = C(t) - C(t +/- deltat).
takeTimeDiff.cf(cf, deltat = 1, forwardshift = FALSE)Object of type cf, a particle correlation function which shall be shifted.
integer. the time shift
boolean. If set to TRUE, the forward finite
difference is used instead of the backward one
