MACADAMIA Sloan Digital Sky Survey Asteroid Photometry, Measurements, and Images
收藏资源简介:
This dataset contains data from the Multi-Archive Catalog of Asteroid Detections And Measurements for Interactive Access (MACADAMIA), specifically of numbered asteroids observed serendipitously by the Sloan Digital Sky Survey (SDSS). photometry_archive_20201027.db is a SQLite database containing data corresponding to a search of the SDSS image archive conducted on 2020 May 1 of all numbered asteroids known at the time, which yielded 2.84 million search results, 1.98 million detections that were determined to actually be within the field of view of the identified image, and 993,777 successfully measured detections. Preview images of all detections and non-detections where the object was determined to be within the field of view of an identified image are collected in the detection_previews_*tar.gz files in this dataset, indexed by detection_id in the photometry database and listed under preview_image_file in the detection_data table. photometry_archive_20210927.db contains an update to the SDSS search, containing data corresponding to a search of the SDSS image archive conducted on 2021 July 2 of all numbered asteroids known at the time, which yielded 2.96 million search results, 2.06 million detections that were determined to actually be within the field of view of the identified image, and 1.02 million successfully measured detections. Previews of additional detections identified in this updated search may not be available due to data loss in a system failure in August 2023.
本数据集源自交互式访问小行星探测与测量多档案目录(Multi-Archive Catalog of Asteroid Detections And Measurements for Interactive Access,缩写MACADAMIA),具体包含斯隆数字巡天(Sloan Digital Sky Survey,SDSS)偶然观测到的已编号小行星数据。 photometry_archive_20201027.db 是一个SQLite数据库,收录了2020年5月1日针对当时已知所有已编号小行星开展的斯隆数字巡天图像档案检索结果。本次检索共得到284万条检索结果,其中198万次探测被确认实际处于对应成像视场范围内,最终成功获得993777条有效测量探测数据。本数据集内的detection_previews_*tar.gz文件打包了所有符合视场条件的探测与非探测目标的预览图像,这些图像以探测ID(detection_id)作为索引,在探测数据表(detection_data)中通过preview_image_file字段进行标注。 photometry_archive_20210927.db 是本次斯隆数字巡天检索的更新版数据库,收录了2021年7月2日针对当时已知所有已编号小行星开展的斯隆数字巡天图像档案检索结果。本次检索共得到296万条检索结果,其中206万次探测被确认实际处于对应成像视场范围内,最终成功获得102万条有效测量探测数据。由于2023年8月的系统故障导致数据丢失,本次更新检索中新增探测目标的预览图像可能无法获取。
