AVS to FITS Conversion: FAQ

What are AVS files?

The AVS image file format is associated with Stardent's Application Visualisation Software (AVS), a currently obsolete program which was popular during the early 1990s. An AVS file contains a bitmap image created using this software. Stardent was a fairly well-known manufacturer of graphics workstations, but it was unable to compete with other upcoming brands, such as IBM, HP and Silicon graphics, and was dissolved in 1994.

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.
