simdata is under active development, documentation may lag reality, please email rindebet at nrao.edu with any questions - It's my job to help you use this software
Steps to simulation
pdf presentation explaining the same things as below
1. Install CASA
simdata inputs look like this:
the links below describe the various sections of inputs
2. Input Model - Preparing a patch of sky for simdata to pseudoobserve. Sample Model Images
3. Antenna List - how to specify the positions and diameters of your antennas or stations.
4. Specifying Observation - how to set up what/when/how you want to observe, and the output image details
5. Corrupting Observation - (Optional) For added realism, corrupt your visibilities with thermal and phase noise.
6. Deconvolve Image (Optional) Go back from the calculated visibilities to a synthesis image
