DASCH数据处理流水线和多次曝光板处理
The DASCH Data Processing Pipeline and Multiple Exposure Plate Processing
摘要：
数字访问天空世纪@哈佛（DASCH）是一个项目，以收集约525,000天文板在哈佛学院天文台举行。本文介绍了DASCH数据处理流水线的概述，特别强调多次曝光板的处理。这种感光板扩大了感光乳剂的动态范围，并通过最大限度地减少感光板显影过程中的变化而提高了光度测定的准确性。本文探讨了两种方法：重复使用astrometry.net（Lang et al. 2010）和本地相关搜索。这两个程序都产生了对管道有用的额外质量控制检查。
英文摘要：
Digital Access to a Sky Century @ Harvard (DASCH) is a project to digitize the collection of approximately 525,000 astronomical plates held at the Harvard College Observatory. This paper presents an overview of the DASCH data processing pipeline, with special emphasis on the processing of multiple-exposure plates. Such plates extended the dynamic range of photograph emulsions and improved photometric accuracy by minimizing variations in plate development procedures. Two approaches are explored in this paper: The repetitive use of astrometry.net (Lang et al. 2010) and local correlation searches. Both procedures have yielded additional quality control checks useful to the pipeline.
