image_to_vis#
- xrayvision.imaging.image_to_vis(image, *, u, v, phase_center=<Quantity [0., 0.] arcsec>, pixel_size=<Quantity 1. arcsec / pix>)[source]#
Return a Visibilities object created from the image and u, v sampling.
- Parameters:
image (Quantity) – The 2D input image
u (Quantity) – Array of u coordinates where the visibilities will be evaluated
v (Quantity) – Array of v coordinates where the visibilities will be evaluated
phase_center (Quantity | None) – The coordinates the phase_center.
pixel_size (Quantity | None) – Size of pixels, if only one value is passed, assume square pixels (repeating the value).
- Returns:
The new Visibilities object
- Return type:
