An error evaluation template for use with imaging spectro-polarimeters

Accurately identifying and bounding error sources in imaging spectro-polarimeters is a challenging task. Here we present an error evaluation methodology intended as an organizational tool for both itemizing and quantifying sources of error in polarimetric instruments. Associated with each source of error are both a metric and test by which these errors may be quantified. Using this procedure, we examine the accuracy and precision of a particular imaging Stokes vector hyper-spectral polarimeter. A subset of the identified error sources are selected and propagated through the system. These measured error quantities are then used to put absolute error bounds on the data acquired by our instrument. These measured error quantities are further documented and presented in the form of an error evaluation sheet.
