I have conducted a survey of a number of eclipsing RS CVn binaries to search for the presence of extended matter associated with the component stars. Previous evidence indicates that this extended matter is more like solar quiescent prominences than other structures such as plage; as such, it is most identifiable when viewed off the stellar limb. In eclipsing systems, the matter can be seen indirectly as it obscures a portion of the eclipsed star's limb. My survey has identified some systems in which this is the case. Parameterization of the physical extent of the extended matter is a geometrical problem wherein the amount of obscuration caused by the prominence depends on its size and orientation as well as its optical depth in the line of interest. I have done this using a Simplex algorithm which I have developed and specifically tailored to the problem at hand. I classify the extended components I have seen and discuss their effect on the spectral profiles. Other spectral diagnostics provide clues as to their origin, and I discuss this in the context of the present "solar analogy" paradigm.
