论文摘要
如今,经常使用专用软件(所谓的“管道””来处理现代天文仪器的原始数据,这些软件主要在自动化操作中运行。在本文中,我们描述了在ESO Paranal天文台操作的多单元光谱探索器(MUSE)集成仪的数据减少管道。该光谱仪是一台复杂的机器:它在其24个整体场单元中记录了1152个单独的空间元素的数据。有效处理此类数据需要复杂的软件,高度的自动化和并行化。我们描述了所有处理步骤的算法,这些算法详细介绍了基于校准和科学数据的操作,并解释了如何将原始科学数据转换为校准的数据包。我们最终检查了选定的过程和输出数据产品的质量,并证明管道提供了准备科学分析的数据流程。
Processing of raw data from modern astronomical instruments is nowadays often carried out using dedicated software, so-called "pipelines" which are largely run in automated operation. In this paper we describe the data reduction pipeline of the Multi Unit Spectroscopic Explorer (MUSE) integral field spectrograph operated at ESO's Paranal observatory. This spectrograph is a complex machine: it records data of 1152 separate spatial elements on detectors in its 24 integral field units. Efficiently handling such data requires sophisticated software, a high degree of automation and parallelization. We describe the algorithms of all processing steps that operate on calibrations and science data in detail, and explain how the raw science data gets transformed into calibrated datacubes. We finally check the quality of selected procedures and output data products, and demonstrate that the pipeline provides datacubes ready for scientific analysis.
