create_w_term_like

create_w_term_like(im: Image, w, phasecentre=None, remove_shift=False, dopol=False) → 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 phasecentre is used as the delay centre for the w term (i.e. where n==0)

Parameters:

• im – template image

• phasecentre – SkyCoord definition of phasecentre

• w – w value to evaluate

• remove_shift

• dopol – Do screen in polarisation?

Returns:

Image
