Wu ------------ UVCS Activity: Ly-a flat field -------------- Synoptic load and start for Oct 10, 1997 SOHO Activity: -------------- EOF Staff: M. Huber/S. Fineschi: Lead Observer/Instr. Ops. Sci. ---------- R. O'Neal: Commander A. Modigliani: Planner R. Wu: Data Processor Command file: 97.10.09.15:03:52.cmd.log Activity: 1) flat field Sequence: 97.10.08_flat_d.tcl, 97.10.09_flat_a.tcl, 97.10.08_flat_e.tcl, 97.10.09_flat_b.tcl 97.10.09_flat_c.tcl SCI_SPEC: LYA Flat Field for portion of LYA detector around the blocker. This calibration is needed for the electron scattered Ly-a data. OBS_PROG: Calibration SCI_OBJ: Calibration; Flat Field OBJ: Coronal Hole CMP_NO.: CMP_NAME: Duration: start: 97.10.09.16:17 end: 97.10.10.00:55 ONUMs = 5365 (25 exposures) (97.10.08_flat_d.tcl) 5366 (25 exposures) (97.10.09_flat_a.tcl) 5367 (15 exposures) (97.10.08_flat_e.tcl) 5368 (25 exposures) (97.10.09_flat_b.tcl) 5369 (25 exposures) (97.10.09_flat_c.tcl) !! NB: seq. 97.10.08_flat_e.tcl was run to verify the "stripes" observed !! in the previuos run of flat filed seqs. That measurement confirmed !! that the "stripes" corresponds to regions with lower efficiency due to !! the charge extracted by the intense Ly-alpha illumination in those !! areas. The lower gain due to the lower HV setting reduces the number !! of events with energy higher than the XDL threshold Instrument configuration: - Pointing: Sun Center - Roll: PA = 0 (18762) - Mirror: 1.4 Ro - Occulter: 1.5 mm underocculting - LYA Slits: 300 um - OVI Slits: OVI DET OFF - LYA GRTPOS: as to image Ly-a along detector around blocker - OVI GRTPOS: OVI DET OFF - LYA mask: EL_Temp - OVI mask: OVI DET OFF Fits files: q97.10.09.16:15:59.lya.dat q97.10.09.17:55:47.lya.dat q97.10.09.19:35:58.lya.dat q97.10.09.20:41:55.lya.dat q97.10.09.22:48:04.lya.dat 2) Synoptic Sequence Load and Start Sequence: Synoptic1:Start SCI_SPEC: Synoptic studies OBS_PROG: Synoptic SCI_OBJ: Synoptic OBJ: Entire Corona Duration: start: 97.10.10.01:13 end: 97.10.10.16:07 ONUMs = 5370 (57 exps) 5371 (24 exps) 5372 (36 exps) 5373 (24 exps) 5374 (57 exps) 5375 (24 exps) 5376 (aborted) Instrument configuration: - Pointing: Sun center - Roll: W, NW, N, NE, E, SE, S, SW - Mirror/Occulter: 1.5, 1.75, 2.0, 2.25, 2.50 Ro (Polar scan) 1.5, 1.75, 2.0, 2.25 Ro (MidLat scan) 1.5, 1.7, 1.9, 2.2, 2.6, 3 Ro (Equat. scan) 1.5 mm overocculting - LYA Slits: 50 um - OVI Slits: 300 um - LYA GRTPOS: 130000 - OVI GRTPOS: 75000 - LYA mask: LYA_Syn130 in slot 2 - OVI mask: OVI_Syn75 in slot 2 Fits Files: q97.10.10.01:12:12.lya.dat q97.10.10.01:12:12.ovi.dat q97.10.10.01:12:12.vld.dat q97.10.10.04:30:50.lya.dat q97.10.10.04:30:50.ovi.dat q97.10.10.04:30:50.vld.dat q97.10.10.05:56:48.lya.dat q97.10.10.05:56:48.ovi.dat q97.10.10.05:56:48.vld.dat q97.10.10.10:03:24.lya.dat q97.10.10.10:03:24.ovi.dat q97.10.10.10:03:24.vld.dat q97.10.10.11:29:17.lya.dat q97.10.10.11:29:17.ovi.dat q97.10.10.11:29:17.vld.dat q97.10.10.14:47:51.lya.dat q97.10.10.14:47:51.ovi.dat q97.10.10.14:47:51.vld.dat
