	---------

	1) South Coronal Hole Observation 

	Sequence: 04.07_hole1OVIonly.tcl

	SCI_SPEC: Characterization of a south 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=185 degrees.
