FOS Instrument Science Report #095 Location of FOS Polarimetry Spectra 6/93 by Anuradha Koratkar and Cynthia Taylor Abstract excerpted from this report: The location of the spectra for plarimetric obsercvations were determined for both the read and blue detectors using calibration maps obtained on May 12 1993 (proposal ID 4697). The analysis for the blue side detector showed that the positions of the spectra are relatively stable. Since the in-orbit GIMP corrections are now conducted routinely, the red detector can be used for polarimetry. Hence, in-flight Y-bases for the red detector were determined for the first time.
