	3) Coronal Hole Intensity Study
   
	Sequence: 09.10_HoleIntOVI.tcl, n = 8, m = 0, p = 0, r = 0, e = 0

	SCI_SPEC:  The purpose of this series of observations is to track the 
		   changes in polar coronal hole intensities that are occuring 
		   during the current prolonged solar minimum, and compare them 
		   to the intensities observed at the time of the previous 
		   minimum.
