With the goal to discover Earth-like extrasolar planets aroundlow-mass stars, the CARMENES project will start in 2015 to obtainhigh-precision near-infrared spectroscopy from several hundredstars. Novel data extraction and analysis algorithms are required tosuccessfully apply high-precision velocimetry methods at longwavelengths. We propose to optimize data extraction and analysistechniques for m/s Doppler measurements at near-infrared wavelengths,which is central to several upcoming and planned velocimetry missions,to utilize our tools to maximize the performance of the CARMENESsurvey, and to search for planets in this survey. The proposal hasthree main scientific goals: (i) the optimization of data extractionand analysis techniques for the use at near-infrared wavelengths, (ii)the search for extrasolar planets, and (iii) the extraction ofhigh-quality spectra from the CARMENES stars.

为了发现低质量恒星周围的类地太阳系外行星，CARMENES 项目将于 2015 年启动，从数百颗恒星中获取高精度近红外光谱。需要新颖的数据提取和分析算法才能在长波长下成功应用高精度测速方法。我们建议优化近红外波长的米/秒多普勒测量的数据提取和分析技术，这对于几个即将到来和计划中的测速任务至关重要，利用我们的工具最大限度地提高卡梅内斯调查的性能，并在其中寻找行星民意调查。该提案有三个主要科学目标：（i）优化近红外波长使用的数据提取和分析技术，（ii）寻找太阳系外行星，以及（iii）从卡梅内斯恒星中提取高质量光谱。
