The Hubble Space Telescope Advanced Camera for Surveys Quick-Look Application

摘要

The Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) instrument has been acquiring thousands of images each year since its installation in 2002 (via Servicing Mission 3B) and subsequent restoration in 2009 (via Servicing Mission 4). The ACS Quicklook project (acsql) provides a means for users to view all on-orbit ACS image and header data through a browser interface, an API to build custom datasets through relational queries, and a platform on which to build automated instrument calibration and monitoring routines. This is accomplished through the various system components: (1) a ~40 TB filesystem, which stores all publicly-available ACS data on disk, (2) a MySQL database, which stores all publicly-available FITS header data for each ACS filetype and header extension, (3) a Python/Flask-based web application, which allows users to navigate and display any public ACS archival data, and (4) a Python code library, which serves as the filesystem, database, and website API. ACS Quicklook is intended to be extended to support the forthcoming James Webb Space Telescope mission.
