Analysis
simdata will calculate and display up to 6 of the following:
- The array - plotants
- UV coverage
- The synthesized dirty beam (psf)
- (the first three are only for interferometric simulation - not useful for single-dish only simulation)
- The sky model image at full original resolution and scale
- The sky model image convolved with the output beam
- The output clean image
- The residual of the clean deconvolution
- The difference between the input model convolved with the beam and the output image
- The fidelity, which is the output divided by the absolute value of the difference, except that a floor equal to the RMS noise is applied to the difference image to avoid dividing by zero.
