OVI detector flat field for redundant path. Exposures "lost" due to loss of telemetry from DSS-66 "added back on" in subsequent commanding. Grating positions listed below are, therefore, presented out of order.

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.
