Convert SLK to FIT

An SLK file, standing for Symbolic Link File, is a specialized file type used primarily in spreadsheet applications to facilitate data exchange. Originally introduced by Microsoft for its Multiplan spreadsheet program in the 1980s, the SLK format was later adopted by other spreadsheet software due to its simplicity and efficiency. These files are composed of ASCII text and include symbolic references to cells, allowing for easy parsing and manipulation of spreadsheet data. The primary use of SLK files is to enable seamless data transfer between different spreadsheet programs, ensuring compatibility and preserving the integrity of the data during exchange.

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.
