Since many FITS files contain data that is outside the dynamic range of F/x and Morph's 8-bit channel depth, the Importer examines the file for the total dynamic range represented and then scales that linearly and proportionally into the range 0-255 as greyscale. For instance, if a FITS file contained values that ranged from 20,000 to -10,000, the Importer will scale the data so that -10,000 is zero, 5,000 is 128, and 20,000 is 255. In this way, the Importer uses WinImages F/x's entire available dynamic range to represent the data. It is then often useful to apply F/x's channel map operator with a custom palette to further help visualize the file data.

 Tip:

There are many types of FITS files that are not loadable using this Importer. Many FITS files contain data that is not image data such as one dimensional tables, or even plain text. The Importer will correctly fail to load these files.
