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:

Inputs.png

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
