An attempt at determining the science requirements for polarimetric calibration for SIR-C is reported. A model describing the effect of miscalibration is presented, followed by an example showing how to assess the calibration requirements specific to an experiment. The effects of miscalibration on some commonly used polarimetric parameters are also discussed. It is shown that polarimetric calibration requirements are strongly application dependent. In consequence, the SIR-C investigators are… Expand
