DEFINE IMAGE

        [SIC\]DEFINE IMAGE Var1 File1 Key1 [Var2 File2 Key2 [...]] [/GLOBAL]

    Define  variables  associated  to both the content and the header of the
    GILDAS images located in the files, if specified. This command acts as a
    combination  of DEFINE HEADER and DEFINE TABLE. It accepts the same key-
    words (KeyN) as DEFINE TABLE. If the keyword is READ, the  header  vari-
    ables are mapped ReadOnly, otherwise they are mapped ReadWrite.

    See  HELP DEFINE HEADER for a description of the individual header vari-
    ables.
