论文摘要
随着近红外高分辨率光谱的成熟,尤其是在用于精确径向速度的情况下,数据降低在从原始数据到校准,提取和校正数据的如何使用千分之一三分之一的像素的必需精度的校正数据方面面临着前所未有的挑战。在这里,我们提出了Apero(减少观察结果的管道),特别针对Canada-France-france-hawaii望远镜(Spectropolarimètrefrarouge,cfht)上的近红外光谱仪。在本文中,我们概述了Apero,并详细介绍了Spiou的减少程序。 Apero提供了经过矫正的2D和1D光谱以及偏光仪的产品。 Apero在Spirou的当前5年寿命中,在天空(通过LBL算法)上实现了精确的稳定径向速度测量值,至少可至少约2 m/s。
With the maturation of near-infrared high-resolution spectroscopy, especially when used for precision radial velocity, data reduction has faced unprecedented challenges in terms of how one goes from raw data to calibrated, extracted, and corrected data with required precisions of thousandths of a pixel. Here we present APERO (A PipelinE to Reduce Observations), specifically focused on SPIRou, the near-infrared spectropolarimeter on the Canada--France--Hawaii Telescope (SPectropolarimètre InfraROUge, CFHT). In this paper, we give an overview of APERO and detail the reduction procedure for SPIRou. APERO delivers telluric-corrected 2D and 1D spectra as well as polarimetry products. APERO enables precise stable radial velocity measurements on sky (via the LBL algorithm), good to at least ~2 m/s over the current 5-year lifetime of SPIRou.
