create_awterm_convolutionfunction

create_awterm_convolutionfunction(im, make_pb=None, nw=1, wstep=1000000000000000.0, oversampling=9, support=8, use_aaf=True, maxsupport=512, pa=None, normalise=True, polarisation_frame=None)[source]

Fill AW projection kernel into a GridData.

Parameters:

  • im – Image template

  • make_pb – Function to make the primary beam model image (hint: use a partial)

  • nw – Number of w planes

  • wstep – Step in w (wavelengths)

  • oversampling – Oversampling of the convolution function in uv space

Returns:

griddata correction Image, griddata kernel as GridData
