	1) North Coronal hole observation
   
	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.
