	1) Observation of the North Coronal Hole

	Sequence: 03.12_hole5short2.tcl, n53min=9

	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=357 degrees.
