UVCS MISSION LOG ---------------- Date: 2 February 1997 ----- Last revision: 97/02/03 (Wu) -------------- File Name: 97.02.02.a.log ----------- Compiled by: S. Fineschi ------------ UVCS Activity: VLC Stray Light Polarization -------------- Start of Synoptic for 3 Feb SOHO Activity: -------------- EOF Staff: S. Fineschi (Lead scientist) ---------- A. Modigliani Command file: Activity: 1) VLC Stray Light Polarization Sequence: U_QuickPolScan:Take, Interact_Take:10s SCI_SPEC: The purpose of these measurements is to characterize the possible polarization of the instrument stray light. Specifically, the experiment is aimed at measuring the degree of linear polarization of the light diffracted by the external occulter.
