论文摘要

我们介绍了生长印度望远镜的设计和性能，该望远镜是一个0.7 M的机器人望远镜，专门用于时间域天文学。该望远镜配备了4K后刷的相机，可在5分钟的暴露量中获得0.82度的视野和敏感性。自定义软件处理天文台操作：达到高天内观测效率（> 〜80％），并可以快速响应机会目标。数据处理管道能够执行PSF光度法以及用于瞬态搜索的图像减法。我们还概述了生长印度望远镜对伽马射线爆发的研究的贡献，电磁对应物与引力波源，超新星，Novae，Novae和太阳系对象。

We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illuminated camera giving a 0.82-degree field of view and sensitivity of m_g ~20.5 in 5-min exposures. Custom software handles observatory operations: attaining high on-sky observing efficiencies (>~ 80%) and allowing rapid response to targets of opportunity. The data processing pipelines are capable of performing PSF photometry as well as image subtraction for transient searches. We also present an overview of the GROWTH-India telescope's contributions to the studies of Gamma-ray Bursts, the electromagnetic counterparts to gravitational wave sources, supernovae, novae and solar system objects.
