#Telescope Simulator
Simulates visibilities given a sky model, and then images. The visibilities are simulated using MeqTrees and/or LWIMAGER. You can image using LWIMAGER, WSCLEAN, or the CASA imager (clean task).
To run this simulator, you need supply the simulator a configuration file; parameters.json is an example.
This is what you need to install

Once you got docker set up. You can run the simulator as follows:
- Download casapy
$ make download - Build container
$ make build - Run simulation
$ make run config=json_config_file
Please Note
- You only have to run
make downloadonce - You will need to re-build the container (run
make build) everytime the pipeline changes - The container will always be rebuilt using cached data, unless you run
make force-build, in which case everything will be rebuilt from scratch. - You don't have to re-build the container each time you modify your config file. But your config file has to be placed in input/
