	3) Detector Characterization: Vignetting Function Measurement

	Sequence: 07.09_occ_OVI.tcl

	SCI_SPEC: Vignetting function tests.  Observe signal in OVI channel 
		  as a function of occulter position at fixed mirror 
		  position 2.5 Ro. Scan occulter 1.3 - 2.3 Ro (0.80-8.70 mm)
		  This test is to determine the change of mirror efficiency 
		  with time.
