Gardner ------------ UVCS Activity: Studies of VLC Polarization w/and w/o Offset in -------------- Coronal Hole; Check for polarizer-induced occulter modulation Start synoptic for February 10 Load "special" observations for February 10 SOHO Activity: None -------------- EOF Staff: S. Fineschi: Lead Scientist --------- L. Gardner Command files: 97.02.09.15:22:18.cmd.log Activity: 1) VLC Polarization Tests w/offpointing/Polarizer induced occulter modulation Sequence: 97.02.09_VLCMS_LDG_3.tcl 97.02.09_LDG.tcl 97.02.10_silvio 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.
