Uzzo: Commander, Planner Command file: 09.12.22.13:10:50.cmd.log Activity: --------- 1) North Coronal Hole Weekly Study (2.4 Ro) [Continued] Sequence: HoleOVIweek.tcl 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.
