class pycrtools.tasks.minibeamformer.MiniBeamformer(ws=None, parfile=None, **kwargs)

This beamformer is deliberately designed to be fast, lightweight and simple.

Forms a beam in one given direction from a set of input antennas.

Input parameters

antpos [default value: None ]

Antenna positions.

beamformed_fft

Resulting beamformed FFT signal.

blocksize

Number of samples in a block.

direction [default value: (0.0, 90.0) ]

Pointing as (az, el) tuple in degrees in the LOFAR convention.

fft_data [default value: None ]

Input FFT data.

frequencies [default value: None ]

Frequencies.

nantennas

Number of antennas.

nfreq

Number of frequencies.

run()

Run the task.
