Parameters ---------- x : array_like Sample times. y : array_like Measurement values (must be registered so the mean is zero). freqs : array_like Angular frequencies for output periodogram. Returns ------- pgram : array_like Lomb-Scargle periodogram. Raises ------ ValueError If the input arrays `x` and `y` do not have the same shape.
