Installation

$ conda install numpy scipy pyyaml astropy

Usage

There are two ways to use this code: as a python library or via the CLI. More documentation on using the library can found in the docs, especially in the getting started tutorial A more involved introduction to the CLI can be found in the CLI tutorial.

As a taste, the simplest possible usage is by using the CLI as follows:

$ sense calc-sense <SENSITIVITY_CONFIG_FILE.yml>

Other options to the calc-sense program can be read by using:

$ sense calc-sense --help

An example config file is in this repository under example_configs/sensitivity_hera.yml, which details the various parameters that can be set. In all, three configuration files are required – one defining an observatory, another defining an observation, and the sensitivity one already mentioned.

The CLI can also be used in a two-step process, by running:

$ sense grid-baselines <OBSERVATION_CONFIG_FILE.yml>

and then:

$ sense calc-sense <SENSITIVITY_CONFIG_FILE.yml> --array-file=<ARRAY_FILE.pkl>

where the ARRAY_FILE is produced in the first step (and its location is printed during the execution).

Running Tests

An example of how to run tests is in the Github Workflow testsuite.yaml. In short, just run pytest in the top-level directory after installing the package.
