	1) UVCS Door Closed Safing

	Sequence: Manual

        SCI_SPEC: UVCS placed in Door Closed Safe configuration for Momentum
		  Management and Station Keeping manuevers.  Detector High 
		  Voltage ramped down and turned off (with detector HV 
		  commanding disabled afterward): Expected Limit Violation
		  sheet in place during ramp down.  UVCS aperture door closed 
		  partially (708 steps).  Mirror / Occulter Mechanism heater 
		  to 100% duty cycle (64 Engineering Units), and Spectrometer 
		  Assembly heater to 60% duty cycle (128 EU).  Flight 
		  Operations Team then instructed to use UVCS door closed 
		  temperature limits (by running procedure o_uvcs_doorlim)
		  for time during which UVCS will be in this state (ELV sheet 
		  is also disregarded at this time).

	2) UVCS in Door Closed Safe Configuration

	Sequence: 

	SCI_SPEC: Detector High Voltage ramped down and turned off, UVCS 
		  door partially closed (708 steps).  Door Closed temperature
		  limit monitoring (by Flight Operations Team) in place. 
		  Mirror / Occulter Mechanism heater on at 100% duty cycle 
		  (64 Engineering Units).  Spectrometer Assembly heater on at 
		  60% duty cycle (128 EU).
