Kohl: Lead Scientist --------- R. Wu Commander Y.-K. Ko: Planner M. Uzzo Command file: 06.04.11.12:24:00.cmd.log Activity: --------- 1) South Coronal Hole Observations Sequence: 06.04_holeOVI24.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. Roll positions are VL-corrected for PA=180 degrees.
