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.

CARMENES项目的目标是在低质量恒星周围发现类地太阳系外行星，该项目将于2015年启动，以获得数百颗恒星的高精度近红外光谱。新的数据提取和分析算法需要成功地应用高精度的测速方法在长波长。我们建议优化数据提取和分析技术，用于近红外波长的m/s多普勒测量，这是几个即将到来的和计划中的测速任务的核心，利用我们的工具来最大限度地提高CARMENES调查的性能，并在这次调查中寻找行星。该提案有三个主要科学目标：（一）优化数据提取和分析技术，以用于近红外波长，（二）搜索太阳系外行星，以及（三）从CARMENES恒星提取高质量光谱。
