Sit&Stare at 1.5 Rsun and scan through OVI grating positions from 160376 to 185988, with reference position of 172000. Mirror is fixed at the crosstalk position for 168204 for 1.5 Ro --> Mirror X-Talk: choose x-talk at 168204, central position, because this gives an error of +- 13 engineering units (about .004 solar radii), and saves lots of bytes and possible errors.

Goal is to measure the properties of a high-latitude 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 polar coronal holes. Roll positions are VL-corrected for PA=130 degrees.
