create_vpterm_convolutionfunction

create_vpterm_convolutionfunction(im, make_vp=None, oversampling=8, support=6, use_aaf=False, maxsupport=512, pa=None, normalise=True, polarisation_frame=None)

Fill voltage pattern kernel projection kernel into a GridData.

The makes the convolution function for gridding polarised data with a voltage pattern.

Parameters:

• im – Image template

• make_vp – Function to make the voltage pattern model image (hint: use a partial)

• oversampling – Oversampling of the convolution function in uv space

Returns:

griddata correction Image, griddata kernel as GridData
