	2) Detector Characterization: Vignetting Function Measurement

	Sequence: 05.06_cal_occ.tcl

	SCI_SPEC: Vignetting function tests.  Observe signal in OVI channel 
		  as a function of occulter position for several fixed mirror 
		  positions:

		    mirror 2.5 Ro  scan occulter 1.3 - 2.3 Ro (0.8-8.7 mm)
		    mirror 3.5 Ro    "      "    2.1 - 3.3 Ro (7.12-16.62mm)
		    mirror 4.5 Ro    "      "    3.0 - 4.3 Ro (14.24-24.53mm)

		  This test is to determine the change of mirror efficiency 
		  with time.
