③Observation Studies
17-GHz images of two phenomena, an eruptive prominence and enhance emissions associated with soft x-ray coronal holes, are shown in Fig.2 and
Fig.3, respectively, which are obtained by the Nobeyama Radioheliograph (Fig.1) and processed by the steer-type algorithm with contour-trim
level of 0.8 and loop gain of 0.2.
In the images of both phenomena, the steer-type algorithm shows good performance of restoration for complicated structures among the variety of components, and also shows ten times less computational time, as compared with the conventional CLEAN algorithm.
