pol_matrix_multiply

ska_sdp_datamodels.science_data_model.pol_matrix_multiply(cm, vec, polaxis=0)

Matrix multiply of appropriate axis of vec […,:] by cm

For an image vec has axes [nchan, npol, ny, nx] and polaxis=1 For visibility vec has axes [row, nchan, npol] and polaxis=2 For visibility vec has axes [row, ant, ant, nchan, npol] and polaxis=4

Parameters:

• cm – matrix to apply

• vec – array to be multiplied […,:]

• polaxis – which axis contains the polarisation

Returns:

multiplied vec
