ESO User Support and Observation Preparation for VLTI Science Operations
AI总结：
从用户视角介绍VLTI观测能力增强及相关工具进展，如关键升级、第二阶段工具功能等，总结观测统计与调度考虑，展示新教程，提及存档数据流和社区参与，还给出未来干涉测量设施操作经验教训。
AI中文摘要：
我们从用户导向的视角展示了VLTI观测能力的近期增强，以及欧洲南方天文台（ESO）的观测处理工具和VLTI的端到端操作模型的新进展。关键升级包括在UTs使用激光导星进行GRAVITY+库德引导、提高GRAVITY和MATISSE的极限星等以及新的MATISSE窄场离轴模式，均由简化统一的模板结构支持。第二阶段工具现可生成寻星图并选择库德导星和条纹跟踪器目标，不久还将提供扩展准备功能和uv覆盖可视化。我们总结了快照、天体测量、成像和时间序列观测的使用统计，概述VLTI调度考虑并展示新视频教程。2026年起有了GRAVITY简化视见度的存档数据流。VLTI操作中的社区参与不断增加。最后我们确定了未来干涉测量设施的操作经验教训，包括端到端数据流和用户支持模型、灵活调度、高级观测准备工具以及协调社区支持的重要性，以确保广大社区能够使用复杂的干涉测量设施。
英文摘要：
We present recent enhancements to VLTI observing capabilities from a user-oriented perspective, together with new developments in ESO's Observation Handling Tools and end-to-end operations model for VLTI. Key upgrades include GRAVITY+ Coudé guiding with laser guide stars at the UTs, improved limiting magnitudes for GRAVITY and MATISSE, and a new MATISSE narrow-field off-axis mode, all supported by a streamlined, uniform template structure. Phase 2 tools now enable finding-chart generation and the selection of Coudé guide stars and fringe-tracker targets, and will soon offer expanded preparation features and uv-coverage visualisation. We summarise usage statistics for snapshot, astrometric, imaging, and time-series observations, outline VLTI scheduling considerations, and present new video tutorials. Starting in 2026, an archive data stream of reduced GRAVITY dispersed visibilities has become available. Complementary community engagement in VLTI operations continues to grow. We close by identifying operational lessons for future interferometric facilities, including the importance of an end-to-end data-flow and user-support model, flexible scheduling, high-level observation-preparation tools, and coordinated community support to keep complex interferometric facilities usable by a broad community.
