Convert FIT to ART

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.

The ART file extension, associated with PFS: 1st Publisher, stands for "AOLpress Raster Technology". Developed by America Online (AOL), this format was designed to optimize image download speeds over slow internet connections by employing high compression ratios. ART files store single, highly compressed images, allowing for incremental rendering similar to progressive JPEGs. While it was useful in the past, the ART format has largely been replaced by more modern image formats.
