Flexible Image Transport System (.fit)

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 CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
