	2) North Coronal Hole Weekly Study (1.7 Ro)
	
	Sequence: HoleOVIweek.tcl

	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.

	OBS_PROG: Primary: Sensitivity
		  Sub Obj: Spatial Coverage

	SCI_OBJ:  Plasma Properties...Proton and Ion Temperatures

	OBJ:      Coronal Hole
