1. Introduction Welcome to the documentation for the code, data, and plotting scripts corresponding to the paper titled "Method Comparison for Simulating Non-Gaussian Beams and Diffraction for Precision Interferometry". This repository contains resources to replicate the simulation results presented in the paper. Please carefully review the instructions below to ensure the successful execution of the code, data generation, and plotting. 2. Dependencies Before running the code, it is necessary to install IfoCAD (version 2022/10, git commit adf19a5b) in your environment. Please note, that IfoCAD is currently prepared for publication. However, because IfoCAD is not yet publically available, we provide here likewise the data generated by IfoCAD. Here is the introduction page of IfoCAD: https://www.aei.mpg.de/ifocad. Additionally, the plotting scripts require the installation of gnuplot. 3. Directory Structure The code, data, and plotting scripts are organized according to the structure of the paper's sections. Each section corresponds to a specific folder. Here is a brief overview of the file structure: Section2/: Code, data, and plotting scripts for Section 2 Section3/: Code, data, and plotting scripts for Section 3 ... 4. Running the Code Step 1: Install Dependencies Ensure IfoCAD is installed. The open-source release is anticipated soon. Also, make sure gnuplot is installed for the plotting scripts. Step 2: Run the Code Navigate to the specific section folder and to run the code. 5. Generating Data After running the code, the generated data will be stored in the file path configured in the code. Utilize this data for further analysis and visualization. 6. Plotting Scripts Each section's plotting scripts are located in their respective folders. Run these scripts sequentially to generate plots consistent with those presented in the paper. Make sure to have gnuplot installed for proper execution. For any issues or questions during usage, feel free to contact us. Thank you for using our resources!
