English: Figure 2. Validation and potential of polarimetric MEM imaging [42]. (a) Full-polarimetric images of 3C 279 from 7 mm VLBA data using CLEAN and MEM are nearly identical when the MEM image is convolved with the CLEAN beam. (b) Compared against a model image of Sgr A* at 1.3 mm, the normalized root-mean-square error of a polarimetric MEM reconstruction achieves its minimum at finer angular resolution than does CLEAN. MEM and CLEAN images reconstructed at the optimum beam sizes for each technique and the nominal beam size demonstrate that polarimetric MEM achieves superior resolution and image fidelity. |
