Convert IPYNB (Jupyter Notebook) to FIT

The IPYNB file extension stands for "Interactive Python Notebook" and is used exclusively with Jupyter Notebook. It is a JSON file format that contains a complete record of user sessions, including code, narrative text, equations, and visualizations. The IPYNB files facilitate reproducible research and easy sharing of data analysis workflows. Originating from the IPython project, Jupyter Notebook has expanded its capabilities to support multiple programming languages, making it a versatile tool in the data science and machine learning communities. The format's history traces back to the early 2010s when it was developed to enhance interactive computing and collaborative work.

The Flexible Image Transport System (FIT) file format, widely used in the field of astronomy and imaging, is designed for the storage, transmission, and processing of digital images and data. Developed in the late 1970s by the International Astronomical Union (IAU), the FIT format has become the standard for storing complex data arrays, including metadata. FIT files are particularly valued for their ability to preserve high-precision scientific data and extensive headers, making them indispensable in both professional and amateur astronomical research.
