Cranmer: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner R. Hauck M. Uzzo Command file: 02.07.25.16:13:01.cmd.log Activity: --------- 1) Observation of the North Polar Coronal Hole Sequence: 02.06_hole1.tcl SCI_SPEC: Characterization of the north polar coronal hole. Goal is to measure the properties of the 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 those non-polar coronal holes. Roll positions are VL-corrected for PA=7 degrees.
