Running the IFU simulator

While not part of the FRIDA data reduction pipeline, the fridadrp-ifu_simulator script was created with the intention of generating simulated images to begin the development and testing of reduction recipes.

After installing megardrp, the IFU simulator should be available in your system:

(venv_frida) $ fridadrp-ifu_simulator --version

0.1.dev122+g9cc23a9

The script accepts a number of arguments, which are displayed when invoking the script name without any parameter:

(venv_frida) $ fridadrp-ifu_simulator

The simulator uses a file called scene as its basic input, which contains information about the image to be simulated. This file must be written in YAML format, which allows the user to conveniently define the geometry and type of spectrum of the astronomical sources to be simulated.
