论文摘要
我们介绍了Fornax Deep Survey（FDS）的第一个数据发布，这是一项成像调查，使用使用宽大成像仪Omegacam安装在SDSS u'，g'，r'的VST上的宽场成像仪，以及覆盖Fornax Galaxy群集和Infnax Galaxy群集和In Infnax fornax a组的波段。 FDS是Nova（以前称为焦点-PI：R。F. Peletier）和INAF（作为Vegas -Pis的一部分-PIS：M。Capaccioli和E. iodice）之间的联合项目。在约28平方度的面积上，暴露时间约为9小时，这项调查是一个遗留数据集，用于研究Fornax Galaxy群集成员和输入的Fornax fornax a组至〜28 mag/arcsec^2的表面亮度极限（1个sigma表面表面亮度（在1 Arcsecond^2区域）的属性环境中，该属性的作用是对新属性的调查，以调查新的参数。星系人口。在处女座群集之后，FORNAX是与我们的第二个最近的星系群，并且具有不同的质量和进化状态，它提供了有价值的比较，可以理解对星系和星系簇的各种进化影响。有关调查的详细信息可以在A. Venhola，R。F。Peletier，E。Laurikainen等，2018，A＆A 620，165中找到。在此版本中，存在181 GB的（压缩）拟合使用系统减少的文件。将在即将发行的版本中提供具有完整源样本的目录，其中包括集群的矮星系部分，球状簇和背景星系。数据产品可通过https://archive.eso.org/scienceportal/home?publ_date=2020202020202020202020202020202020202020202020202020202020202020202020-26获得数据产品
We present the first data release of the Fornax Deep Survey (FDS), an imaging survey using using the wide-field imager OmegaCAM mounted on the VST in the SDSS u', g', r', and i'-bands covering the Fornax Galaxy Cluster and the infalling Fornax A Group. FDS is a joint project between NOVA (previously called FOCUS - PI: R. F. Peletier) and INAF (as part of VEGAS - PIs: M. Capaccioli and E. Iodice). With exposure times of about 9 hours over an area of ~28 square degrees, this survey is a legacy dataset for studies of members of the Fornax Galaxy Cluster and the infalling Fornax A Group down to a surface brightness limit of ~28 mag/arcsec^2 (1-sigma surface brightness over a 1 arcsecond^2 area) and opens a new parameter regime to investigate the role of the cluster environment in shaping the properties of its galaxy population. After the Virgo cluster,Fornax is the second nearest galaxy cluster to us, and with its different mass and evolutionary state, it provides a valuable comparison that makes it possible to understand the various evolutionary effects on galaxies and galaxy clusters. Details about the survey can be found in A. Venhola, R. F. Peletier, E. Laurikainen et al., 2018, A&A 620, 165. In this release, 181 Gb of (compressed) fits files reduced using the system are present. Catalogues with the complete sample of sources including dwarf galaxies part of the cluster, globular clusters, and background galaxies will be provided in forthcoming releases. The data products are available via the ESO Science Portal at https://archive.eso.org/scienceportal/home?publ_date=2020-08-26
