The method of reduction, its strengths and weaknesses, and suggestions for improvements are discussed. Generally excellent agreement in white light photometry and polarimetry of the North Polar coronal region is most encouraging, while the discrepancies in other regions should provide insights into instrumental limitations or directions for future refinements.
