波鸿南银盘巡天：II。2010-2015年监测的1 323平方度的后续测量和多滤光片测光
The Bochum Survey of the Southern Galactic Disk: II. Follow-up measurements and multi-filter photometry for 1323 square degrees monitored in 2010-2015
摘要：
本文是描述在智利Cerro Armazones附近的波鸿大学进行的南银河系盘调查（GDS）的系列文章中的第二篇。Haas等人（2012年，论文I）介绍了调查设计以及观测和数据的特点。他们在2011年的50多次观测中，在50平方度的区域内确定了约2200颗变星。在这里，我们提出了第一个完整版本的GDS涵盖所有268场与1323平方度沿银河系的磁盘，包括修订的数据从文件I。对单个场的观测次数多达272次，最长时间跨度为2010年9月至2015年5月。我们总共检测到64151个变量源，这些变量源在一个目录中列出，包括它们的一些属性和它们的光变曲线。与国际变星指数（VSX）和全天自动巡天（ASAS）的比较表明，56794这些来源是以前未知的变量。此外，我们提出了UBVr 'i'z'测光GDS内的所有来源，导致在一个新的多色目录中检测到的至少一个过滤器的近16x10^6源。在Via Lactea调查（VVV）中，GDS和近红外VISTA变量在约300平方度的重叠区域中相互补充，以便将来进行比较研究。
英文摘要：
This paper is the second in a series describing the southern Galactic Disk Survey (GDS) performed at the Universitätssternwarte Bochum near Cerro Armazones in Chile. Haas et al. (2012, Paper I) presented the survey design and a the characteristics of the observations and data. They identified ~2200 variable stars in an area of 50 square degrees with more than 50 observations in 2011. Here we present the first complete version of the GDS covering all 268 fields with 1323 square degrees along the Galactic disk including revised data from Paper I. The individual fields were observed up to 272 times and comprise a maximum time span between September 2010 and May 2015. We detect a total of 64151 variable sources, which are presented in a catalog including some of their properties and their light curves. A comparison with the International Variable Star Index (VSX) and All Sky Automated Survey (ASAS) indicates that 56794 of these sources are previously unknown variables. Furthermore, we present UBVr'i'z' photometry for all sources within the GDS, resulting in a new multi-color catalog of nearly 16x10^6 sources detected in at least one filter. Both the GDS and the near-infrared VISTA Variables in the Via Lactea survey (VVV) complement each other in the overlap area of about 300 square degrees enabling future comparison studies.
