| Abstract: |
From the VLBA archival data of SgrA* at 43 GHz, we made synthesis images by applying solutions from self calibration method using the previously estimated shape of SgrA* as a model image. From comparisons with the previous estimations using closure amplitude and/or phase, we found that consistent sizes and shapes of SgrA* at 43GHz are obtained from our images. Admitting the bad observational conditions with low elevations and poor u-v, the VLBA imaging of SgrA* at 43 GHz can be performed with better reliability than the present common recognition. |
