在太阳活动21周中,法国墨东天文台和北京天文台密云站分别在169MH_2和460MH_2观测到Ⅰ型源的自行。密云站的观测是根据Ⅰ型源通过一维干涉仪栅瓣时刻确定源的位置,因而在源存在自行时,只能在一些合理的假设下推测其运动。另外,我们干涉仪的时间分辨率太低,只能用于研究噪暴的连续成份。在文献[3,4]中所涉及的源的运动仅指连续谱成份。
During the 21 weeks of solar activity, the French MoDong Observatory and the Beijing Astronomical Observatory’s Miyun Station observed type I sources themselves at 169MH 2 and 460MH 2, respectively. The Miyun station observes the source location based on the type I source through the grating lobes of the one-dimensional interferometer. Therefore, when the source exists on its own, the motion can only be estimated under some reasonable assumptions. In addition, the time resolution of our interferometer is too low and can only be used to study the continuous components of noise storms. The motions of the sources involved in [3, 4] refer only to the continuum components.
