FITS - Flexible Image Transport System

FITS is an image data file format for encoding astronomical data. The WCS (World Coordinate System) conventions map elements in data arrays to standard physical coordinates in the sky. FITS has provisions for image metadata encoded in an ASCII header at the beginning of files.

Extensions

FITS World Coordinate System (WCS)

An extension of FITS that enables data to be defined to specify physical, or world coordinates within each pixel in an image. The conventions were orignally proposed in 2002 then incorporated into the 3.0 release of the FITS standard.

Tools
