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.

DEC Six Pixels (.six)

The SIX file extension, short for "six pixels", is a bitmap graphics format developed by Digital Equipment Corporation (DEC) for their terminals and printers. Introduced initially to send bitmap graphics to DEC dot matrix printers like the LA50, SIX later facilitated the transfer of soft fonts to terminals such as the VT220. This format encodes images using a series of six-pixel-high patterns, making it efficient for transmitting graphics over 7-bit serial links. Rediscovered around 2010, SIX remains in use with modern terminal emulators for tasks like video playback.
