Source code for toto.filters.detrend

""" Remove linear trend along axis from data.
   
    Parameters
    ~~~~~~~~~~
    input_array : panda obj
        The input data.
    Type : {'linear', 'constant'}, optional
        The type of detrending.
        If ``type == 'linear'`` (default),
            The result of a linear least-squares fit to `data` is subtracted
            from `data`.
        If ``type == 'constant'``,
            only the mean of `data` is subtracted.

	Note
