ska-sim-mid¶
This package collects RASCIL scripts for various SKA-MID simulations: continuum imaging, continuum imaging with direction-dependent effects, high data rate observations, and observation sizing.
Instructions¶
To install these scripts, use git:
git clone https://gitlab.com/ska-telescope/sim/ska-sim-mid.git
Or download the source code from https://gitlab.com/ska-telescope/sim/ska-sim-mid
None of these simulations need to be installed into the python path. Instead please set the environment variable SMSROOT to the location of code:
export SMSROOT=/path/to/code
RASCIL must be installed - the options are via pip, git clone, or docker. The simplest approach is to use pip. In the ska-sim-mid directory, do:
pip3 install -r requirements.txt
A script can be run as:
export SMSROOT=`pwd`
cd sizing/scripts
sh make_sizes.sh
The resource files for the SKA direction-dependent MID simulations are 80GB in size and are kept on the Google Cloud Platform. The python command line tool gsutil allows for interacting with the Google Cloud Platform:

After installing gsutil, you may download the resources as follows:
cd resources
gsutil -m rsync -r gs://ska1-simulation-data/ska1-mid/beam_models/ beam_models
gsutil -m rsync -r gs://ska1-simulation-data/ska1-mid/screens screens
