Measure efficiency as a function of aperture width using occulter widths of: mm: 49.05, 4.75, 40.35, 10.29, 30.86, 20.57 EU: 28382, 41167, 30905, 39577, 33651, 36618 Note: 60.12mm (25162) and 2.37mm (41848) dropped for 2008 OBS_PROG: Calibration SCI_OBJ: Calibration...Vignetting Function OBJ: Theta Oph (star) CMP_NAME: CMP_NUM: Duration: start: 2008.12.11.14:08 end: 2008.12.11.17:57 ONUMs = 24980 (97 exps) Instrument configuration: - Pointing: Sun center - Spacecraft Roll: 180 Degrees - Roll: 127.5, 129.0 Degrees (9205, 9478) - Mirror: 9.66 - 9.35 Ro - Occwidth: 49.05, 4.75, 40.35, 10.29, 30.86, 20.57 mm - LYA Slits: 100 um - OVI Slits: 100 um - LYA GRTPOS: 100000 - OVI GRTPOS: 45000, 237000 - OVI MCP Voltage: 200 - OVI mask: OVI_303_8x2 in slot 3 Fits Files q08.12.11.13:57:19.ovi.dat 2) South Polar Coronal Hole Observations Sequence: 08.11_hole.tcl, n = 2, m = 2, p = 0, r = 0, 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=180 degrees.
