	---------

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

	SCI_SPEC: Following completion of the second 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, TakeOVI_TxN 120 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.

	3) OVI Detector Dark Rate Diagnostic
   
	Sequence: OVI_dark_chk 26378 51551

	SCI_SPEC: Determine Dark count rate for OVI detector. Instrument 
                  rolled to coronal hole, 5.0 Ro with 0.8 mm exposed mirror. 
                  Script engages OVI filter and then disengages it at end.
