raw_cf correlation function by 'places' time-slicesshift a raw_cf correlation function by 'places' time-slices
shift.raw_cf(cf, places)raw_cf container
Integer (possibly a vector), number of time slices that the correlation function
should be shifted by. Can be positive or negative. This can either
be a single value such that a shift by this many time slices will be
applied to every measurement or it can be a vector of values of the
same length as the number of measurements in cf. In that case,
a different shift will be applied to each measurement. This is useful
if it is important to preserve the absolute time coordinates of a
correlation function until some time-dependent transformations
have been applied.
Returns an object of class raw_cf, shifted compared to the input object.
The correlation funtion \(C(t)\) is shifted in time to produce: $$C'(t) = C(t+places)$$ using periodic boundary conditions in time.
