ARN to FITS Conversion: FAQ

What are ARN files?

ARN is a rare image file format associated with the Astronomical Research Network, an American association formed in 1989. ARN files contain astronomical information and images, and can be created using software programs developed by the Network for PCs and Macs. The format is, however, incompatible with most regular image viewers, so we recommend converting it to a more accessible format.

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.
