NAME File types DESCRIPTION All stageII datafiles have the FITS (Flexible Image Transport System) dataformat. The filetypes used are identified by the value of the CONTENT keyword in the primary FITS header. A "type" dependant suffix, by default appended to the name of every file created, provides merely a clue to the type. A program, requiring a certain type of a file, will append the default suffix to the name supplied StageII filetypes content suffix description ??? generic fits file, no special meaning for StageII software.
