dft_filter_frequency_channel¶
- sofia_redux.scan.filters.filters_numba_functions.dft_filter_frequency_channel(data, fch, rejection_value, rejected, n_frames)[source]¶
Apply DFT filtering for a given frequency channel.
- Parameters:
- datanumpy.ndarray (float)
The data to filter of shape (pow2ceil(n_frames),) in real-space for a single channel.
- fchint
The frequency channel.
- rejection_valuefloat
The filter rejection value for the
fchchannel.- rejectednumpy.ndarray (float)
The current rejected overall values (in Fourier space). This is updated in-place, so must be correct on entry and be the same shape as
data(pow2ceil(n_frames),).- n_framesint
The number of integration frames.
- Returns:
- None
