Basic Information on im2uv
Task: im2uv
Purpose: Convert an image to visibilities.
Categories: uv analysis
This Fourier transforms an image and writes the result as a
visibility file. Thus the uv plane sampling pattern is a
cartesian grid. Many of the uv variables are given reasonably
arbitrary values to make the output dataset appear mildly
sensible.
Key: model
Input image model. No default. The model should have units of
Jy/pixel. eg. a clean component model. Only a two-dimensional
model is handled.
Key: out
Output visibility dataset. No default.
Key: region
The region of interest in the model. The model is treated as
zero outside the region of interest. See the help on region
for more information.
Key: select
Normal visibility data selection. See the help on select for
more information. Currently only 'uvrange' selection is supported.
