The construction of astronomical image database and development of usersupport system

在这一年中，我们重点开发了东京大学木索天文台和冈山天体物理天文台CCD图像的数据存档系统。因此，我们已经完成了MOKA（三aka OkayamaKiso数据档案系统）的构建，该系统可以查询两个天文台的数据并快速查看它们。MOKA是日本首个地面观测数据存档系统，可以作为SUBARU望远镜等大型观测数据保存系统的原型。MOKA已被一些有关天文学家使用，他们发现了一些需要改进的地方，以构建更有用的系统。此外，我们现在正在开发新的更大的数据档案系统“MOKA 2”，具有更先进的功能。在MOKA的发展过程中，我们还为天文学家开发了各种支持系统。例如，我们开发了“名称解析器”。它为用户提供他们只知道其名称的对象的正确坐标。目前，数据库中已经安装了100万个对象的信息，“名称解析器”可以在1秒内找到指定对象的正确坐标。“名称解析器”可以与MOKA一起独立运行。同时，我们也开始建设包含天文目录中大量信息的数据库。作为第一步，我们在数据库管理器中安装了Guide Star Catalog (GSC)，并开发了一个软件，该软件目前正在冈山天文台使用，用于绘制选定的天体。

In this year, we put emphasis on evelopment of data archival system for CCD images obtained at the Kiso Observatory of Tokyo University and the Okayama Astrophysical Observatory. As a result, we have completed to construct the MOKA (Mitaka OkayamaKiso Data Archival System), which make possible to query the data from both observatories and quick-looking of them. MOKA is the first archival system for the data by ground-based observatories in Japan, and it can be the proto-type of which maintain more large ammount of data, such as those from SUBARU telescope. MOKA has been used by some concerning astronomers, and some points which to be improved are found by them for constructing more useful system. Addtionally, we are now on the way of developing new and larger data archival system "MOKA 2", with more advanced functions.In the development of MOKA,we also developed varios support system for astronomers. For example, we developed "Name resolver". It gives users the correct coordinates of the objects of which they know only their names. Currently, the information of 1 million objects have been installed in the database, and "Name resolver" can find the correct coordinates within 1 second for the specified object. "Name resolver" can run independently with MOKA.We have also begun to construct the database which includes many information in astronomical catalog. As a first step, we installed Guide Star Catalog (GSC) in the database manager and developed a software, which is now in use at Okayama Observatory, for plotting the selected objects.
