These must be formatted according to the following FORTRAN sequence:OPEN (UNIT = NL, FILE = FNAME, STATUS = ‘OLD’ [,FORM=’UNFORMATTED’])DO 1 I = 1, IXIF (BINARY) THENREAD(NL) X(I), BX(I)ELSEREAD(NL,*) X(I), BX(I)ENDIF1 CONTINUEwhere ›éQí and ú›é í are the longitudinal coordinate and field component at node é í of the mesh. Binary file namesFNAME must begin with B . ‘Binary’ will then automatically be set to ‘.TRUE.’.2 Sumperimposing (summing) field maps is possible. To do so, pile up file names with ’SUM’following each name but the last one. e.g., in the following example, 3 field maps are read and summed˜:myMapFile1 SUMmyMapFile2 SUMmyMapFile3(of course, these maps must all have their mesh defined in identical coordinate frame).
