With the goal to discover Earth-like extrasolar planets around low-mass stars, the CARMENES project is operating two new spectrographs to obtain high-precision near-infrared spectroscopy from several hundred stars. Novel data calibration, extraction, and analysis methods are used to apply high-precision velocimetry methods at long wavelengths. In this project, we aim to develop and optimize data extraction and analysis techniques for m/s Doppler measurements at near-infrared wavelengths, which is central to several upcoming and planned velocimetry missions. Furthermore, we want to investigate in detail the spectrographs' performance in order to identify and overcome obstacles to reach m/s precision in Doppler measurements. In the context of the proposed Research Unit on CARMENES science exploitation, the proposal has four main scientific goals: (i) optimized data reduction and spectral analysis with a focus on the near-infrared, (ii) determination of radial velocities, (iii) optimization of the quality of the CARMENES M-dwarf survey, and (iv) quality assurance.
