Abstract

This contribution describes improvements to the Baikal-GVD alert system related to alert visualization which could clarify the alert data and its possible relation to astrophysical phenomena. The Baikal-GVD online data processing and alert system was launched at the beginning of 2021. It is designed for fast online neutrino event reconstruction and, when a potential signal from an astrophysical source is detected, sending an alert message to collaboration members. It also searches for coincidences between internal alerts and other astrophysical experiment alerts. The databases schema used to store the alert data (MariaDB, InfluxDB, MongoDB) is described. Automation of data analysis and visualization processes occurs using specialized Python libraries (Matplotlib, Astropy, etc.), which provide an API for that. The capabilities of the Grafana software system for storing visualized data with the ability to share are also explored. One of the main tasks of our alert system is switch to real-time mode with a low latency mode in signal reception both by the Baikal-GVD trigger and in receiving and responding to an external alert.

将数据库应用于贝加尔-GVD Neurtino 望远镜增强型跟踪系统的数据可视化

摘要本文介绍了贝加尔-全球气压变化警报系统在警报可视化方面的改进，这些改进可以澄清警报数据及其与天体物理现象的可能关系。贝加尔-GVD 在线数据处理和警报系统于 2021 年初启动。该系统旨在快速在线重建中微子事件，并在检测到来自天体物理源的潜在信号时，向合作成员发送警报信息。它还能搜索内部警报与其他天体物理实验警报之间的巧合。介绍了用于存储警报数据的数据库模式（MariaDB、InfluxDB、MongoDB）。数据分析和可视化过程的自动化使用专门的 Python 库（Matplotlib、Astropy 等），这些库提供了相关的应用程序接口。此外，还探讨了 Grafana 软件系统存储可视化数据的能力以及共享能力。我们警报系统的主要任务之一是切换到实时模式，在接收贝加尔-海拔高度触发器信号以及接收和响应外部警报时采用低延迟模式。
