论文摘要
在VLT Coude焦点上观察可以通过结合多个VLT单元望远镜的光（UTS；尽管在轻型列车中有一些损失）来提高收集区域。 Coude的仪器具有显着的操作灵活性优势：它可以连接到任何可用的UT，并且“额外”仪器可以帮助更好地匹配观测约束与当前条件。通过对现有火车的修改，它甚至可以与不同的UTS并行观察。在这里，我们考虑了通用VLT Coude纤维喂养的低分辨率设施光谱仪（临时称为卡布奇诺） - 适用于快速随访和微弱瞬变的表征，用于对瞬态的后期监测以及在差条件下或在暮色期间的快速分类。像班级的任何乐器一样，卡布奇诺咖啡可用于解决各种科学问题。如果建筑物的成本基于现有硬件，则可以大大降低建筑物的成本。
Observing at the VLT Coude focus can boost the collecting area by combining light from multiple VLT unit telescopes (UTs; albeit with some losses in the light train). An instrument at the Coude enjoys significant operational flexibility advantage: it can be attached to any available UT and the "extra" instrument can help to match better the observing constraints with the current conditions. With modifications to the existing train it can even observe in parallel with ESPRESSO with different UTs. Here we consider a general purpose VLT Coude fiber-fed low-resolution facility spectrograph - provisionally named Cappuccino - suitable for rapid follow up and characterization of faint transients, for late-stage monitoring of transients and for rapid classification under poor conditions or during twilight. Like any instrument of its class, Cappuccino can be used to address diverse set of science questions. The building cost can be reduced greatly if it is based - with modest changes - on existing hardware.
