	UVCS Activity:  Ramp down and turn off LyA detector
        --------------	Turn on and ramp up OVI detector
			Conduct OVI Stimulus Pulse Test (no exps taken due to
			problem with discriminator settings)
			Conduct OVI detector dark rate diagnostic
			Move LyA grating from 100000 to 67000

	1) LyA detector ramped down and turned off
   
	Sequence: Manual

	SCI_SPEC: Following completion of the first LyA component of the synoptic
		  observation, the LyA MCP is ramped down and turned off.

	2) OVI detector turn on, ramped up, and OVI Stimulus Pulse Test
	   conducted
   
	Sequence: Manual, TakeOVIexps.tcl 0 0 2

	SCI_SPEC: After switching off LyA detector, the OVI detector is turned on
		  a stimulus pulse test is completed

		  After powering on OVI detector, discriminator settings were discovered
		  to be incorrect. Discriminator settings were commanded to their nominal
		  values.
		  
		  No stimilus pulse exposures were taken.
