       2) Observation of an Equatorial Coronal Hole

        Sequence: 02.12_hole1.tcl

	SCI_SPEC: Characterization of an equatorial coronal hole.
		  Goal is to measure the properties of a non-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 polar coronal holes.

                  Roll positions are VL-corrected for PA=270 degrees.
