This repository contains the code used to conduct the analysis in Setterholm et al. (2024). Both the parametric models and image reconstruction codes are written in the Julia programming language¹, however each of these two analyses uses a different version of the OIFITS.jl library, so they are seperated into their own directories.

To run the code, simply cd into either the ImageReconstruction or ParametricModelFitting directory, start a Julia REPL session, press the ] key to enter the package manager mode, and enter in activate . to install/load the relevant library dependencies. Once this is complete, press the Backspace key to exit package manager mode and then use the include function to load the .jl files.

For the parametric modeling code, modify the paths/analysis as needed in the example.jl file for your system before including it. Once you have issued the include("example.jl") command in the Julia REPL, the model fitting will begin automatically.

For image reconstruction, you will need to use the mkimage function from the Julia REPL directly passing in the path to the raw (merged) OIFITS file that you would like to image.

Footnotes

1. Specifically, Julia v1.9.4 was used in the article but there should be no issue running this code on newer 1.x versions of Julia ↩
