摘要: We present the Collection of Elemental Routines for Echelle Spectra (CERES). These routines were developed construction automated pipelines reduction, extraction and analysis spectra acquired with different instruments, allowing obtention homogeneous standardised results. This modular code includes tools handling steps processing: CCD image reductions, identification tracing echelle orders, optimal rectangular extraction, computation wavelength solution, estimation radial velocities, rough fast atmospheric parameters. Currently, CERES has been used to develop thirteen spectrographs, namely CORALIE, FEROS, HARPS, ESPaDOnS, FIES, PUCHEROS, FIDEOS, CAFE, DuPont/Echelle, Magellan/Mike, Keck/HIRES, Magellan/PFS APO/ARCES, but can be easily in order deal data coming from other spectrographs. show high precision velocity that achieves some these instruments we briefly summarize results have already obtained using pipelines.
