create_w_term_like

create_w_term_like(im: data_models.memory_data_models.Image, w, phasecentre=None, remove_shift=False, dopol=False) → data_models.memory_data_models.Image

Create an image with a w term phase term in it:

\[\]

I(l,m) = e^{-2 pi j (w(sqrt{1-l^2-m^2}-1)}

The vis phasecentre is used as the delay centre for the w term (i.e. where n==0)

Parameters

• phasecentre –

• im – template image

• w – w value to evaluate (default is median abs)

• remove_shift –

• dopol – Do screen in polarisation?

Returns

Image
