HARPS是一种新的高分辨率纤维馈入光谱仪，专门用于极其精确地测量恒星径向速度。在使用了大约一年之后，包括调试运行，我们报告了非常成功地实施了所采取的措施，以最大限度地提高稳定性，效率和频谱性能。采用同步参考法，短期精度可达0.2 m/s，长期精度可达1 m/s左右。HARPS配备了一个全自动数据简化管道，可以近乎实时地产生太阳系重心径向速度，有望提供无与伦比的数据质量。HARPS将主要用于搜寻系外行星和星震学领域。首先，令人兴奋的科学结果证实了这些预期。
HARPS is a new high resolution fibre-fed spectrograph dedicated to the extremely precise measurement of stellar radial velocities. After being used for about one year including the commissioning runs we report a very successful implementation of the measures taken to maximise stability, efficiency and spectral performance. Using the Simultaneous ThAr Reference Method a short term precision of 0.2 m/s during one night and a long term precision of the order of 1 m/s have been achieved. Equipped with a fully automated data reduction pipeline that produces solar system barycentric radial velocities in near real-time, HARPS promises to deliver data of unequalled quality. HARPS will primarily be used for the search for exoplanets and in the field of asteroseismology. First exciting scientific results confirm these expectations.
