Romoli: Lead Scientist --------- A. Modigliani A. Ciaravella R. O'Neal R. Wu Command files: 97.02.26.15:24:33.cmd.log Activity: 1) VLC stray light test with offset Sequence: U_PolExp:TakePB SCI_SPEC: Measurement of pB at two heights. At each height the int. occulter is fixed and the instrument is offset. Purpose of the test is to determine if the origin of the polarized stray light is the external occulter diffracted light.
