我们已经开发了一种新技术,称为快速数据分析,用于纳苏干涉仪的无线电瞬态搜索。快速查看数据,根据射电源信噪比(S/N)的彩色图,从漂移扫描数据在空间和时间上生成。一个稳定的光源每天出现在相同的赤经,颜色相同。相比之下,像射电暴这样的瞬态物体在天空中不规则地出现,由此产生的地图将会有零星的斑块。使用这种技术已经探测到无线电瞬变WJN J1443+3439。快速查看的数据是使用条纹检测方法和彩色图像创建的过程创建的,我们在这里描述,我们展示了Cyg A, 3C 48, Mrk 501和2005年发现的瞬态射电源WJN J1443+3439的实际彩色图像。
We have developed a new technique, called quick‐look data analysis, for radio transient searches at the Nasu Interferometer. Quick‐look data, a color map according to the radio source signal‐to‐noise ratio (S/N), were generated spatially and temporally from drift‐scanning data. A steady source appears at the same right ascension with the same color every day. In contrast, transient objects such as radio bursts appear irregularly in the sky, and the resulting map will have sporadic patches. Radio transient WJN J1443+3439 has already been detected using this technique. The quick‐look data were created using processes that we call the fringe‐detecting method and color image creation, which we describe here, and we show actual color images of Cyg A, 3C 48, Mrk 501, and the transient radio source WJN J1443+3439 found in 2005.
