Wu Command file: 09.07.14.14:40:50.cmd.log Activity: --------- 1) North Polar Coronal Hole Study Sequence: 09.07_hole.tcl, n = 8, m = 1, p = 0, r = 1, e = 0 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=0 degrees.
