    Returns
    -------
-    spectrum: array_like 
+    spectrum : array_like
        2-D array, columns are the periodograms of successive segments.

-    freqs: array_like
+    freqs : array_like
        1-D array, frequencies corresponding to the rows in *spectrum*.

    t : array_like
-        1-D array, the times corresponding to midpoints of segments 
+        1-D array, the times corresponding to midpoints of segments
        (i.e the columns in *spectrum*).

    See Also
    --------
-    psd : differs in the default overlap; in returning the mean of the segment periodograms; and in not returning times.
-    complex_spectrum : A single spectrum, similar to having a single segment when mode is 'complex'.
-    magnitude_spectrum : A single spectrum, similar to having a single segment when mode is 'magnitude'.
-    angle_spectrum : A single spectrum, similar to having a single segment when mode is 'angle'.
-    phase_spectrum : A single spectrum, similar to having a single segment when mode is 'phase'.
+    psd : differs in the overlap and in the return values.
+    complex_spectrum : similar, but with complex valued frequencies.
+    magnitude_spectrum : similar single segment when mode is 'magnitude'.
+    angle_spectrum : similar to single segment when mode is 'angle'.
+    phase_spectrum : similar to single segment when mode is 'phase'.

    Notes
    -----
    detrend and scale_by_freq only apply when *mode* is set to 'psd'.
