論文摘要

Commissioning the Yuan-Tseh Lee Array

[ Oral ]

Kai-Yang Lin (ASIAA), YTLA Team

In the past two years, we have been using the Yuan-Tseh Lee Array (YTLA) for various science verification observations while tuning up the performance of the array. In this talk, I will highlight some of the results showing the characteristics of the array. In the initial test of deep integration, we have found an obstacle, a spurious signal in the system. We used field-subtraction to remove this spurious signal. I will demonstrate our current status of the deep integration using this technique. On the other hand, we have also identified the source of the problem and implemented a solution. Upon verification with on-site testing, we would soon resume the intensity mapping observations with YTLA.
