Imaging (‘xrayvision.imaging’)#

The imaging submodule contains functions to make map and images from visibilities.

xrayvision.imaging Module#

`get_weights`(vis[, scheme, norm])	Return spatial frequency weight factors for each visibility.
`validate_and_expand_kwarg`(q[, name])	Expand a scalar or array of size one to size two by repeating.
`vis_psf_image`(vis, *[, shape, pixel_size, ...])	Create the point spread function for given u, v point of the visibilities.
`vis_psf_map`(vis, *[, shape, pixel_size, scheme])	Create a map of the point spread function for given the visibilities.
`vis_to_image`(vis[, shape, pixel_size, scheme])	Create an image by 'back projecting' the given visibilities onto the sky.
`vis_to_map`(vis[, shape, pixel_size, scheme])	Create a map by performing a back projection of inverse transform on the visibilities.
`generate_header`(vis, *, shape, pixel_size)	Generate a map head given the visibilities, pixel size and shape
`image_to_vis`(image, *, u, v[, phase_center, ...])	Return a Visibilities object created from the image and u, v sampling.
`map_to_vis`(amap, *, u, v)	Return a Visibilities object created from the map, sampling it at give `u`, `v` coordinates.
