Comparison of RMs derived from STAPS and the measurements by Schnitzeler et al. (2019). The sources with only one RM component in Schnitzeler et al. (2019) are marked with red circles. For sources with multiple RM components, the RMs of the first components are plotted and marked with black squares. For the one source with multiple observations, the RMs of the second components are plotted and marked with blue diamonds. The line indicates y = x.
