Ko: Lead Scientist, Planner ---------- R. Wu: Commander M. Uzzo Command file: 02.02.01.19:12:01.cmd.log Activity: --------- 1) Mirror/Occulter Vignetting Function Study Sequence: 02.02_cal_occ.tcl SCI_SPEC: Vignetting function tests. Observe signal in OVI channel as a function of occulter position for several fixed mirror positions: mirror 2.5 Ro scan occulter 1.3 - 2.3 Ro (0.8-8.7 mm) mirror 3.5 Ro " " 2.1 - 3.3 Ro (7.12-16.62mm) mirror 4.5 Ro " " 3.0 - 4.3 Ro (14.24-24.53mm) Do this observation once every several weeks to see if there is any change in efficiency of the exposure mirror with time, especially at the lower edge.
