摘要:

本文介绍了第二次公开数据发布(DR 2)的卡拉尔阿尔托遗产积分领域(CALIFA)调查。200个天体的数据被公开,包括第一次公开数据发布(DR 1)的100个星系。数据是用安装在卡拉阿尔托天文台3.5米望远镜上的积分场摄谱仪PMAS/PPak获得的。每个星系都有两种不同的光谱设置,(i)低分辨率V500设置,覆盖波长范围3745-7500 nm,光谱分辨率为6.0 nm(FWHM),(ii)中等分辨率V1200设置,覆盖波长范围3650-4840 nm,光谱分辨率为2.3 nm(FWHM)。该样本涵盖了0.005和0.03之间的红移范围,在色星等图,恒星质量,电离条件和形态类型的广泛属性。所有发布的立方体都通过最新的管道减少,包括改进的分光光度校准,空间配准和空间分辨率。分光光度法的定标优于6%,空间分辨率中值为2.5”。第二次发布的数据总共包含150多万个光谱。可在http://califa.caha.es/DR2上查阅。

英文摘要:

This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100 galaxies of the First Public Data Release (DR1). Data were obtained with the integral-field spectrograph PMAS/PPak mounted on the 3.5 m telescope at the Calar Alto observatory. Two different spectral setups are available for each galaxy, (i) a low-resolution V500 setup covering the wavelength range 3745-7500 Å with a spectral resolution of 6.0 Å (FWHM), and (ii) a medium-resolution V1200 setup covering the wavelength range 3650-4840 Å with a spectral resolution of 2.3 Å (FWHM). The sample covers a redshift range between 0.005 and 0.03, with a wide range of properties in the Color-Magnitude diagram, stellar mass, ionization conditions, and morphological types. All released cubes were reduced with the latest pipeline, including improved spectrophotometric calibration, spatial registration and spatial resolution. The spectrophotometric calibration is better than 6% and the median spatial resolution is 2.5". Altogether the second data release contains over 1.5 million spectra. It is available at http://califa.caha.es/DR2.
