本文介绍了METIS科学数据处理流水线的设计现状和相应的流水线系统。它将是E-ELT的前三台仪器之一，工作波长在3-19 μm（L/M/N/Q1波段）之间。我们将提供符合欧洲南方天文台（ESO）标准的软件，并将采用最先进的技术来产生科学级数据，主校准框架，质量控制参数和处理仪器效果。该仪器目前提供了本文所列的大量观测模式。由于各种来源的热辐射的巨大影响，在这些波长上对地面仪器进行数据处理特别具有挑战性。我们将全面概述仪器提供的成像模式的数据流系统，并讨论不同成像观察模式的单配方与多配方方法。
We present the current status of the design of the science data reduction pipeline and the corresponding dataflow system for METIS. It will be one of the first three instruments for the E-ELT and work at wavelengths between 3-19 μm (L/M/N/Q1 bands). We will deliver software which is compliant to standards of the European Southern Observatory (ESO), and will employ state of the art techniques to produce science grade data, master calibration frames, quality control parameters and to handle instrument effects. The Instrument currently offers a wealth of observing modes that are listed in this paper. Data reduction for a ground based instrument at these wavelengths is particularly challenging because of the massive influence of thermal radiation from various sources. We will give a comprehensive overview of the data ow system for the imaging modes that the instrument offers and discuss a single recipe versus a multi recipe approach for the different observing modes for imaging.
