| Abstract: |
While the COSTAR mirror assembly installed on the Hubble Space Telescope (HS T) during the second servicing mission effectively restored HST optical capabilities, off-axis reflections from the COSTAR mirrors also introduced a measurable amount of instrument polarization. We developed a methodology to quantify and remove the induced polarization as detected by the FOS spectropolarimeter (Allen 1995), and modified the FOS calibration pipeline to accommodate post-COSTAR FOS Blue spectropolarimetry observations. |
