- Added missing commas in various print statements and function calls for better syntax. - Reformatted code to enhance clarity, including breaking long lines and aligning parameters. - Updated function signatures to use float type for sigma parameters instead of int for better precision. - Cleaned up comments and documentation strings for clarity and consistency. - Ensured consistent formatting in plotting functions and data handling.
