Detailed Description

Given a list of image file names appropriate for the model_image_score class, the variance of the visibility amplitudes are computed at a set of radial and radial locations. These are then added in quadrature to the existing error budget for a given data object. Note that these errors are static, i.e., they are set at construction time and do not vary subsequently.

Warning: Only visibility amplitude and closure phase are implemented. Others are trivial but not yet done.

Todo:: Implement complex visibility and closure amplitudes.
