ASKAP Project AS102: WALLABY Pilot Survey DR2 - Mosaicked Data Cubes and Images

These are full-sensitivity mosaicked data cubes and images of the three fields observed during phase 2 of the WALLABY pilot survey. Mosaics in this collection include: extragalactic spectral-line data cubes and weights cubes. The WALLABY pilot survey DR2 includes observations of three fields in the directions of the NGC 5044 galaxy group, the NGC 4808 galaxy group and the Vela cluster. The NGC 5044 field mosaics cover 120 square degrees and are formed from SBIDs 33879, 34302, 34166, 34275, 31536, 40905, 25701, 25750. The NGC 4808 field mosaics cover 60 square degrees and are formed from SBIDs 33681, 37604. The Vela field mosaics cover 60 square degrees and are formed from SBIDs 33521, 33596. Users of the data are requested to include a reference to the data release paper (Murugeshan et al. 2024, in prep.), the Phase 1 data release paper (Westmeier et al. 2022, PASA, 39, 58), and the WALLABY survey description paper (Koribalski et al. 2020, Ap&SS, 365, 118) in any publication resulting from their analysis.

这些是WALLABY试点调查第二阶段观测的三个区域的全灵敏度镶嵌数据立方体（data cubes）和图像。本集合中的镶嵌数据包括：河外谱线数据立方体和权重立方体（weights cubes）。WALLABY试点调查第二数据发布（DR2）包含对NGC 5044星系群、NGC 4808星系群和船帆座（Vela）星团方向三个区域的观测。NGC 5044区域的镶嵌数据覆盖120平方度，由SBID编号33879、34302、34166、34275、31536、40905的观测数据构成。数据使用者在其分析产生的任何出版物中，均需引用以下文献：数据发布论文（Murugeshan等，2024，待发表）、第一阶段数据发布论文（Westmeier等，2022，《澳大利亚天文学会出版物》，39卷，58页）以及WALLABY调查描述论文（Koribalski等，2020，《天体物理与空间科学》，365卷，118页）。
