BN to FITS Conversion: FAQ

What are BN files?

The BN format is associated with NewsRoom, a desktop publishing program used particularly in the 1980s on Atari 8-bit home computers. Atari was a well-known brand at the time, competing with Commodore and Apple on the home user market. NewsRoom is currently considered obsolete, and so is the BN format. Other similar extensions include NSR and PH.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
