High-Quality Images Based on the Steer Algorithm Decovolution from the Correlation Data Observed with Nobeyama Radioheliograph
After the Makuhari meeting of IAU Colloquium 153 remarkable developments have been made at Nobeyama on high-quality imaging, which applies the Steer algorithm for deconvolution. Considering the importance of this achievement, it is briefly introduced in this report with farther application to a high-resolution narrow field mapping. Some preliminary results are presented for both cases as well as dual-frequency images at 17 and 34 GHz.
