SD0 to FITS Conversion: FAQ

What are SD0 files?

SD0 is part of a group of extensions known as Dali Raw images, together with SD1 and SD2. Each of these formats represents RAW images captured using a Sigma device. Also known as "digital negatives", photos shot in RAW mode capture the image exactly as seen by the lens, without any automatic retouching or balancing of colors, lights etc.

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.
