摘要
本文描述了卡拉阿托遗产积分场巡天 (CALIFA) 的第二次公共数据发布 (DR2)。发布了 200 个天体的数据，其中包括第一次公共数据发布 (DR1) 中的 100 个星系。数据是使用安装在卡拉阿托天文台 3.5 米望远镜上的积分场光谱仪 PMAS/PPak 获得的。每个星系有两种不同的光谱设置可用：(i) 低分辨率 V500 设置，覆盖波长范围 3745-7500 \AA，光谱分辨率为 6.0 \AA (FWHM)；(ii) 中分辨率 V1200 设置，覆盖波长范围 3650-4840 \AA，光谱分辨率为 2.3 \AA (FWHM)。样本覆盖的红移范围在 0.005 到 0.03 之间，在颜色 - 星等图、恒星质量、电离条件和形态类型方面具有广泛的性质。所有发布的数据立方体均使用最新管线进行了还原，包括改进的光度校准、空间配准和空间分辨率。光度校准优于 6%，中值空间分辨率为 2.5"。第二次数据发布总共包含超过 150 万条光谱。数据可通过 http://califa.caha.es/DR2 获取。
