NOTE |
This command is available for any non RGB image regardless of whether it was actually loaded from a FITS format file. For an RGB image, use the Image Info command to view the information header. |
The FITS Header is the part of a FITS Format file where image documentation is stored. FITS format stores all the information about the image in a regular format of Keyword, Value, and Comment, as shown above. Usually the Keyword and Value are of more interest than the Comment. If the Comment is more than a couple of words in length it will extend past the right edge of the small window as shown above. To show the full comment field, resize the window in the normal way.
The FITS Header contents can be edited to change entries, add new information, and to correct errors. See Editing the FITS Header.
