epochs : instance of Epochs
mode : str
Spectrum estimation mode can be either: ‘multitaper’ or ‘fourier’.
fmin : float
Minimum frequency of interest.
fmax : float  np.inf
Maximum frequency of interest.
fsum : bool
Sum CSD values for the frequencies of interest. Summing is performed
instead of averaging so that accumulated power is comparable to power
in the time domain. If True, a single CSD matrix will be returned. If
False, the output will be a list of CSD matrices.
tmin : float  None
Minimum time instant to consider. If None start at first sample.
tmax : float  None
Maximum time instant to consider. If None end at last sample.
n_fft : int  None
Length of the FFT. If None the exact number of samples between tmin and
tmax will be used.
mt_bandwidth : float  None
The bandwidth of the multitaper windowing function in Hz.
Only used in ‘multitaper’ mode.
mt_adaptive : bool
Use adaptive weights to combine the tapered spectra into PSD.
Only used in ‘multitaper’ mode.
mt_low_bias : bool
Only use tapers with more than 90% spectral concentration within
bandwidth. Only used in ‘multitaper’ mode.
projs : list of Projection  None
List of projectors to use in CSD calculation, or None to indicate that
the projectors from the epochs should be inherited.
verbose : bool, str, int, or None
If not None, override default verbose level (see mne.verbose).
