	1) UVCS in Modified Hard Safe Configuration

	Sequence: None

	SCI_SPEC: Following completion of Science Observations, UVCS 
		  is placed into a modified Hard Safe configuration in 
		  preparation for the SOHO Keyhole Period.  

		  OVI Slit is set to 100 microns, instrument is rolled to 
		  the nominal East (35156 Engineering Units).  Detector 
		  High Voltage is ramped down and then turned off, Mirror is 
		  moved to 1.5 Solar Radii with 1.5 mm overocculting.  UVCS 
		  Aperture Door is also closed 708 steps, Internal Mirror / 
		  Occulter Heater set to 100% duty cycle.  Internal 
		  Spectrometer Heater is not turned on.  In addition to 
		  "traditional" Hard Safe configuration, all UVCS detectors 
		  are powered off.

		  FOT use ESR Limit Table, TSU Substitution Heater (Circuit 
		  #84) powered on, using duty cycle of 50%.  Experiment 
		  Offpoint and ESR Flags disabled for Keyhole.
