The previous chapters have described TRANSFER mode and POSITION mode observations. Some FGS error sources are mode-specific, while others are common to both modes. This chapter discusses those uncertainties, both statistical and systematic, which remain after the pipeline calibrations of raw POSITION mode and TRANSFER mode observations. Each step in the calibration procedure leaves its own residuals which contribute to the overall error budget.
