spectrochempy.fsh

fsh(dataset, pts, **kwargs)[source]

Frequency shift by Fourier transform. Negative signed phase correction.

For multidimensional NDDataset, the shift is by default performed on the last dimension.

Parameters:

data (ndarray) – Array of NMR data.
pts (float) – Number of points to frequency shift the data. Positive value will shift the spectrum to the right, negative values to the left.

Returns:

dataset – dataset shifted.

Other Parameters:

dim (str or int, keyword parameter, optional, default=’x’) – Specify on which dimension to apply the shift method. If dim is specified as an integer it is equivalent to the usual axis numpy parameter.
inplace (bool, keyword parameter, optional, default=False) – True if we make the transform inplace. If False, the function return a new dataset.
