项目摘要

The First Light of SDSS has succeeded in the last June of 1998. It is confirmed that the telescope and CCD camera are constructed according as the initial design. The First Light events were performed by the menbers of SDSS Japan Promotion Group(JPG) and also JPG members have attended the test observations and worked for the tuning and test of CCD camera and the complete equipment of main mirror. They have published several Technical Reports with collaborators of the US with respect to newly constructed devices and their performances during these several constructing years. At the completion phase of SDSS, we decided to go a new stage that SDSS is effectively connected with SUBARU telescope. We hope that the detailed observations of new objects found by SDSS and the systematic follow-up observations of catalogued galaxies by SDSS should be done smoothly in near future. Especially, it is important to use common devices in order to get the same qualitative level of data. Then, we sent several JPG menbers to Hawaii at the First Light event and checked the whether the mosaic CCD camera works stably or not. From these results, we got the valuable fundamentaldata for the method of data analysisi and improvement of devices. The JPG menbers have played important roles in the First Light event of SUBARU.These data were analyzed for constructing new instruments which would efficintly connect the results of SDSS and SUBARU.These products will make effective the best use of SDSS and SUBARU.

SDSS的第一盏灯在1998年6月的最后一个光线上取得了成功。可以证实，望远镜和CCD摄像头是根据初始设计构建的。第一个轻型事件是由SDSS日本促销小组（JPG）的Menbers进行的，JPG成员也参加了测试观察结果，并为CCD摄像头的调整和测试和Main Mirror的完整设备而工作。他们已经与美国合作者在这几年的新构建设备及其性能方面发表了几份技术报告。在SDSS的完成阶段，我们决定进入一个新阶段，该阶段有效地与Subaru望远镜相连。我们希望SDSS发现的新对象的详细观察以及SDS对SDSS分类星系的系统后续观察应在不久的将来进行。尤其是，重要的是要使用常用设备以获得相同的定性数据级别。然后，我们在第一次灯光赛事中将几个JPG Minbers派往夏威夷，并检查了Mosaic CCD相机是否稳定工作。从这些结果中，我们获得了数据分析方法和设备改进方法的宝贵基础。 JPG Minbers在Subaru的第一个光明事件中发挥了重要作用。这些数据被分析用于构建可以有效地连接SDSS和Subaru的新仪器的数据。这些产品将有效地最佳使用SDSS和Subaru。
