	1) OVI Detector HV Intensity Characterization

	Sequence: 08.10_GratScanOVI.tcl

	SCI_SPEC: Determine Intensity rate versus High Voltage Setting for 
		  the OVI detector using the OVI doublet at 3 grating
		  positions. Instrument rolled to coronal hole, 1.7 Ro with 
		  standard 1.5 mm overocculting. High Voltage set manually 
		  prior to observation. 

	OBS_PROG: Calibration

	SCI_OBJ:  Calibration

	OBJ:      Coronal Hole

	CMP_NAME: 

	CMP_NUM:  

	Duration: start: 2008.10.18.19:26
		    end: 2008.10.19.20:16

	ONUMs = 24856 (240 exps)
		24857 (240 exps)
		24858 (240 exps)

	Instrument configuration:

		- Pointing:  Sun center

                - Spacecraft Roll:  0 Degrees

		- Roll: 180 Degrees (51551)

		- Mirror/Occulter:  1.7 Ro
                                    1.5 mm overocculting

		- LYA Slit:   100 um
		- OVI Slit:    75 um 

		- LYA GRTPOS: 100000
		- OVI GRTPOS: 223500, 232100, 217000

	2) OVI Detector Dark Rate Diagnostic

	Sequence: OVI_dark_chk.tcl

	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.
