	1) 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.

	OBS_PROG: Calibration

	SCI_OBJ:  Calibration

	OBJ:      Coronal Hole

	CMP_NAME: 

	CMP_NUM:  

	Duration: start: 2008.10.23.17:14
                    end: 2008.10.23.18:15

       	ONUMs =	24873 (12 exps)

	Instrument configuration:

		- Pointing:  Sun center

		- Spacecraft Roll:  0 Degrees

		- Roll: 180 Degrees (51551)

		- Mirror/Occulter:  5.0 Ro
                                    1.5 mm overocculting

	2) OVI Detector HV Intensity Characterization

	Sequence: 08.10_GratScanOshort.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.
