UVCS MISSION LOG ---------------- Date: 8 February 1997 ----- Last revision: 21 February 1997 (Wu) ------------- File Name: 97.02.08.a.log ----------- Compiled by: L. Gardner ------------ UVCS Activity: Studies of VLC Polarization w/and w/o Offset in -------------- Coronal Hole Start synoptic for February 9 SOHO Activity: None -------------- EOF Staff: S. Fineschi: Lead Scientist --------- L. Gardner A. Modigliani C. Benna Command files: 97.02.08.16:17:03.cmd.log Activity: 1) VLC Polarization w/and w/o Offpointing and with Occulter Movements Sequence: 97.02.08_VLCMS_LDG.tcl 97.02.08_LDG.tcl 97.02.08_VLCMS_LDG_2.tcl SCI_SPEC: The purpose of these measurements is to characterize the possible instrumental systematic errors in polarization measurements. Specifically, the experiment is aimed at determining variations of pB as a function of occulter position and offset pointing.
