The extraction of spectra from the two-dimensional detector data, and the subsequent computation of radial velocities and other high-level data products, form the basis of the scientific exploitation of CARMENES. Enhancements of the data reduction pipelines, and adaptations for applications such as transmission spectroscopy of the atmospheres of transiting planets, improve the performance of CARMENES and enable the realization of broader scientific goals. We intend to implement an advanced treatment of detector artefacts, optimize the spectral extraction through two-dimensional modeling of the instrumental point spread function, develop new algorithms for the correction of stellar activity and telluric contamination, enhance the sensitivity for faint targets through an on-chip binning option, and modify the observing procedures for transmission spectroscopy. These measures will help to keep CARMENES competitive with similar spectrographs that have recently become operational.

从二维探测器数据中提取光谱，以及随后的径向速度和其他高级数据产品的计算，构成了科学剥削卡门的基础。增强数据减少管道的功能以及对诸如过境行星大气传输光谱的适应性，改善了卡门氏菌的性能，并能够实现更广泛的科学目标。我们打算实施对探测器伪像的高级处理，通过对仪器点扩散功能的二维建模来优化光谱提取，开发出新的算法，以校正恒星活性和牙槽污染，从芯片binning选项，并修改传输光谱的观察过程。这些措施将有助于使Carmenes与最近变得运行的类似光谱仪的竞争力。
