Abstract : The purpose of the report is to describe and prove by sample data the procedures for calibration of and data reduction from an ultraviolet spectrophotopolarimeter. The objective of the instrument is to measure the intensity and polarization of skylight radiation at altitudes of greater than 100,000 feet. A brief description is given of the instrumentation package and, in particular, the portions directly involved in the calibration procedure. The body of the report contains the procedures used in optical calibration and the general and specific problems in data reduction. Samples of data have been processed through the data reduction program and the programs have been shown to work. However, overall accuracy and probable error have not been carefully evaluated. Three appendices are included which give details of Stokes Vectors and Mueller Calculus, Derivation of the Calibration Formulae, and Computer Programs. (Author)
