APPLAUSE

German astronomical observatories own considerable collection of photographic plates. While these observations lead to significant discoveries in the past, they are also of interest for scientists today and in the future. In particular, for the study of long-term variability of many types of stars, these measurements are of immense scientific value. There are about 85000 plates in the archives of Hamburger Sternwarte, Dr. Karl Remeis-Sternwarte Bamberg, and Leibniz-Institut für Astrophysik Potsdam (AIP). The plates are digitized with high-resolution flatbed scanners. In addition, the corresponding plate envelopes and observation logbooks are digitized, and further metadata are entered into the database. The work is carried out within the project “Digitalisierung astronomischer Fotoplatten und ihre Integration in das internationale Virtual Observatory”, which is funded by the DFG.

德国天文学观测站拥有一批可观的照相底片收藏。尽管这些观测在过去导致了重大发现，但它们对当今及未来的科学家仍具有极大兴趣。特别是，对于研究多种类型恒星的长周期变化，这些测量具有巨大的科学价值。汉堡天文台、卡尔·雷梅斯-巴姆贝格天文台（Dr. Karl Remeis-Sternwarte Bamberg）以及波茨坦的利布尼茨天文物理研究所（Leibniz-Institut für Astrophysik Potsdam，简称 AIP）的档案馆中约有 85000 张底片。这些底片使用高分辨率平板扫描仪进行了数字化处理。此外，相应的底片封套和观测日志也被数字化，并进一步将元数据输入数据库。该工作是在由德国科学基金会（DFG）资助的项目“天文学照相底片数字化及其融入国际虚拟天文台”的框架内进行的。
