摘要
回顾了慧眼-硬X射线调制望远镜(Insight-Hard X-ray Modulation Telescope, 简称慧眼-HXMT)在轨运行前6 yr的本底情况, 包含各载荷在轨本底的地理分布、能谱和时变特征以及长期演化. 除此之外, 还对慧眼-HXMT各载荷在轨本底的估计方法进行了回顾, 综合介绍了各载荷的本底模型以及本底估计的精度. 从总体上看, 慧眼-HXMT的在轨本底符合预期, 各载荷本底模型能够对在轨本底的能谱和光变进行可靠的估计.
Abstract
This paper reviews the in-orbit background of the Hard X-ray Modulation Telescope (HXMT) over the first six years, including the geographical distributions, spectral and temporal characteristics, as well as the long-term evolution of the in-orbit background of each payload. In addition, we also review the estimation methods for the in-orbit background of each payload of Insight-HXMT, providing a comprehensive introduction to the strategies for background estimation and the accuracy of the estimation. Overall, the in-orbit background of Insight-HXMT is consistent with expectations, and the background models for each payload can reliably estimate the spectrum and light curve of the in-orbit background.关键词
