Cranmer: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner M. Uzzo Command file: 03.02.14.17:50:00.cmd.log Activity: --------- 1) Observation of the North Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: Characterization of the north 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=0 degrees.
