快速爆发分析仪I：伽马射线暴的BAT和XRT谱和通量演化
The Swift Burst Analyser I: BAT and XRT spectral and flux evolution of Gamma Ray Bursts
摘要：
背景：伽马射线暴模型预测了能流的宽带谱演化和时间演化。相比之下，标准数据分析工具和数据存储库提供计数率数据，或对所有数据使用单个通量转换因子，忽略光谱演变。目的：在通量单位中产生Swift BAT和XRT光变曲线，其中光谱演变被考虑。研究方法：我们已经开发了软件，使用硬度比信息来跟踪伽马射线暴的光谱演化，从而将Swift上的BAT和XRT仪器的计数率光变曲线转换为准确的、具有演化意识的通量光变曲线。结果如下：雨燕暴分析仪网站（http：//www.swift.ac.uk/burst_analyser）载有雨燕卫星观测到的所有伽马射线暴在三种能量状态下的BAT、XRT和合并的BAT-XRT通量光变曲线。这些光变曲线在数据可用时自动构建和更新，以图形和纯文本格式呈现，可供下载和在研究中使用。
英文摘要：
Context: Gamma Ray Burst models predict the broadband spectral evolution and the temporal evolution of the energy flux. In contrast, standard data analysis tools and data repositories provide count-rate data, or use single flux conversion factors for all of the data, neglecting spectral evolution. Aims: To produce Swift BAT and XRT light curves in flux units, where the spectral evolution is accounted for. Methods: We have developed software to use the hardness ratio information to track spectral evolution of GRBs, and thus to convert the count-rate light curves from the BAT and XRT instruments on Swift into accurate, evolution-aware flux light curves. Results: The Swift Burst Analyser website (http://www.swift.ac.uk/burst_analyser) contains BAT, XRT and combined BAT-XRT flux light curves in three energy regimes for all GRBs observed by the Swift satellite. These light curves are automatically built and updated when data become available, are presented in graphical and plain-text format, and are available for download and use in research.
