Mt. Wilson Solar Photographic Archive Digitization Project

山脉威尔逊太阳照片数字化项目将以数字形式向社区提供卡内基天文台档案中的一些太阳图像。 这些图像可以追溯到1894年，其中许多可以被现代标准判断为质量上乘。 数字化将使用商业扫描技术与印前扫描仪具有16位精度和高达3000 3000点每英寸的空间分辨率。 这些图像将允许对太阳磁性和活动的状态进行各种回顾性分析，并将为许多太阳属性提供100年的时间基线。 世纪是一个温室气体人为排放增加的时期，这可能会导致全球气候变化。 太阳也可能是全球气候变化的一个因素。 数字化所提供的数据将使科学界能够自由地检查太阳磁场行为在同一时间范围内的长期变化，因此可能对解开太阳和人为影响至关重要。

The Mt. Wilson Solar Photographic Digitization Project will make available to the community in digital form a selection of solar images in the archives of the Carnegie Observatories. These images date from 1894 and include many which can be judged to be of superb quality by modern standards. The digitization will use commercial scanning technology with a prepress scanner having 16-bit precision and up to 3000 by 3000 dots per inch spatial resolution. These images will permit a variety of retrospective analyses of the state of solar magnetism and activity, and they will provide a temporal baseline of 100 years for numerous solar attributes. The 20th Century was a period of increased anthropogenic production of greenhouse gases, which may contribute to global climate change. The sun could also be a factor in global climate change. The data provided by this digitization will allow the scientific community to freely examine the secular variation of the sun's magnetic behavior during this same time frame, and may thus be crucial in disentangling the solar and anthropogenic effects.
