Uzzo: Planner Command file: 04.08.18.16:45:00.cmd.log Activity: --------- 1) North Coronal Hole Observation Sequence: 04.07_hole1LyAonly.tcl SCI_SPEC: Characterization of a north 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=3 degrees.
