论文摘要
我们介绍了Pinta,这是一种用于减少升级的巨型米波射电望远镜(UGMRT)RAW PULSAR时正时数据的管道,该数据是为印度Pulsar定时阵列实验开发的。我们提供了PINTA的工作流程和使用及其计算性能和RFI缓解特性的详细描述。我们还讨论了UGMRT不同后端模式之间的相对时间偏移与UGMRT观察频率设置的解释之间的相对时间偏移的新颖和独立的确定,以及它们与工程测试获得的结果的一致性。此外,我们证明了PINTA生成数据产品的能力,这些数据产品可以以PSR J1909-3744为例生产高精度TOAS。这些结果对于使用UGMRT进行精确的脉冲星时间至关重要。
We introduce pinta, a pipeline for reducing the upgraded Giant Metre-wave Radio Telescope (uGMRT) raw pulsar timing data, developed for the Indian Pulsar Timing Array experiment. We provide a detailed description of the workflow and usage of pinta, as well as its computational performance and RFI mitigation characteristics. We also discuss a novel and independent determination of the relative time offsets between the different back-end modes of uGMRT and the interpretation of the uGMRT observation frequency settings, and their agreement with results obtained from engineering tests. Further, we demonstrate the capability of pinta to generate data products which can produce high-precision TOAs using PSR J1909-3744 as an example. These results are crucial for performing precision pulsar timing with the uGMRT.
