K波段多目标光谱仪(KMOS)是一种具有24个可展开低温拾取臂的多目标近红外积分场光谱仪。不可避免的是,数据处理是一项复杂的任务,需要仔细的校准和质量控制。在本文中,我们描述了从原始观测中产生科学质量数据产品所涉及的所有步骤。特别是,我们专注于以下问题:(i)的校准计划,产生的空间和光谱位置的所有照明像素的探测器上的地图;(ii)我们的概念,最小化的插值的数量,限制的情况下,一个单一的重建,同时使用原始数据从多个曝光;(iii)各种插值方法的比较,并评估真正的三维插值方案的性能;(iv)仪器弯曲测量和补偿的方式。最后,我们展示了一些使用管道处理数据的示例。
TheK-band Multi Object Spectrograph (KMOS) is a multi-object near-infrared integral field spectrometer with 24 deployable cryogenic pick-off arms. Inevitably, data processing is a complex task that requires careful calibration and quality control. In this paper we describe all the steps involved in producing science-quality data products from the raw observations. In particular, we focus on the following issues: (i) the calibration scheme which produces maps of the spatial and spectral locations of all illuminated pixels on the detectors; (ii) our concept of minimising the number of interpolations, to the limiting case of a single reconstruction that simultaneously uses raw data from multiple exposures; (iii) a comparison of the various interpolation methods implemented, and an assessment of the performance of true 3D interpolation schemes; (iv) the way in which instrumental flexure is measured and compensated. We finish by presenting some examples of data processed using the pipeline.
