; 12/24/96 KAF edited this with updated angles based on HSI 3D test.
; 1/04/97 KAF edited this with updated angles based on HSI 3D test.
; 7/10/97 dd Add the TOGA_RC keyword
; 8/20/97 dd Change the Rowland spacing to 8788.04 mm.
; 12/15/97 dd Update the periods and rowland spacing for
;             "Prelim report" values.  Add ROWLANDS.
