Cranmer: Lead Scientist ---------- R. Wu: Commander M. Uzzo: Planner Command file: 04.04.09.14:51:00.cmd.log Activity: --------- 1) South Coronal Hole Observation Sequence: 04.02_hole1LyA.tcl SCI_SPEC: Characterization of a south 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=175 degrees.
