本白皮书是为发展飞行任务之间的协同作用而任命的三机构工作组(TAG)的成果，其目的是阐明为了最大限度地提高LSST和欧几里德的综合科学产出，需要进行哪些LSST观测。为了促进LSST计划，我们提供了一系列可能的LSST调查，并基于暗能量品质因数(FOM)的改善提供了明确的衡量标准。为了提供一个可量化的指标，我们提出了五个调查选项，仅使用LSST 10年调查的0.3%至3.8%。我们还提供了这样的信息，以便LSST DDF节奏可能与普通深场、SXDS、COSMOS、CDF和拟议的新的LSST深场(靠近Akari深场南方)中的Euclid{Euclid}相匹配。大型天文观测望远镜(天文望远镜)和欧几里德观测的共同协调将产生大量的协同效应。将来自LSST的光学多波段成像与高分辨率光学和近红外测光和光谱学相结合，不仅将改善暗能量的限制，而且将提供丰富的关于银河系、局部群、局部大尺度结构的科学，甚至是关于再电离时期的第一批星系的科学信息。关于暗能量科学案例的详细论文已经发表(Rhodes等人)。LSST/Euclid联合工作组以及一份描述LSST/Euclid/WFIRST协同作用的白皮书(Jain等人)，我们将在这里简要描述其他科学案例。一份配套的白皮书论证了LSST足迹向北延伸的一般科学理由，我们支持LSST调查南延的白皮书。
This white paper is the result of the Tri-Agency Working Group (TAG) appointed to develop synergies between missions and is intended to clarify what LSST observations are needed in order to maximally enhance the combined science output of LSST and Euclid. To facilitate LSST planning we provide a range of possible LSST surveys with clear metrics based on the improvement in the Dark Energy figure of merit (FOM). To provide a quantifiable metric we present five survey options using only between 0.3 and 3.8% of the LSST 10 year survey. We also provide information so that the LSST DDF cadence can possibly be matched to those of \emph{Euclid} in common deep fields, SXDS, COSMOS, CDFS, and a proposed new LSST deep field (near the Akari Deep Field South). Co-coordination of observations from the Large Synoptic Survey Telescope (LSST) and Euclid will lead to a significant number of synergies. The combination of optical multi-band imaging from LSST with high resolution optical and near-infrared photometry and spectroscopy from \emph{Euclid} will not only improve constraints on Dark Energy, but provide a wealth of science on the Milky Way, local group, local large scale structure, and even on first galaxies during the epoch of reionization. A detailed paper has been published on the Dark Energy science case (Rhodes et al.) by a joint LSST/Euclid working group as well as a white paper describing LSST/Euclid/WFIRST synergies (Jain et al.), and we will briefly describe other science cases here. A companion white paper argues the general science case for an extension of the LSST footprint to the north at airmass < 1.8, and we support the white papers for southern extensions of the LSST survey.
