	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.

	2) North Polar Coronal Hole Study

	Sequence: 09.07_hole.tcl, n = 8, m = 1, p = 0, r = 1, e = 0

	SCI_SPEC: Characterization of a polar coronal hole.
		  Goal is to measure the properties of a polar
		  coronal hole. In particular we are interested in the 
		  coronal conditions (intensities and line widths for 
		  HI Ly-alpha and OVI 1032/1037) as a function of height 
		  and latitude. We will compare these properties with 
		  the ones found in non-polar coronal holes.

		  Roll positions are VL-corrected for PA=0 degrees.

	OBS_PROG: Primary: Sensitivity
		  Sub Obj: Spatial Coverage

	SCI_OBJ:  Plasma Properties...Proton and Ion Temperatures
