	1) Detector Characterization: Vignetting Function Measurement : Part 2

	Sequence: 05.02_cal_occ.tcl,  05.02_cal_occ_mini.tcl, r = 2, 3

	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.

	2) Streamer Properties Over the Solar Cycle

	Sequence: 05.02_StrObsV2.tcl, sw = 1

	SCI_SPEC: A comprehensive study of several streamer properties 
		  including the outflow velocities, abundances, electron
		  densities and temperatures. The spatial distribution
		  of these physical properties are analyzed at multiple 
	          heights within several streamers examined over the 
		  course of the solar cycle.
