| Abstract: |
We present results of a multifrequency synthesis VLBI experiment which employed observations at 1622 and 1707 MHz. Combining data from two frequencies gave a factor of about two improvement in dynamic range over the single frequency images. We estimate map fidelity by comparing the images made separately from each frequency; while the dynamic range is about 1800, the fidelity index is only about 5. |
