Welcome to the Hubble Source Catalog (HSC) Catalog Archive Server Jobs System (CasJobs) service.
There are three basic ways to access the HSC database:
Here are Five things you should know about the HSC before you begin.We recommend running through the CasJobs Use Case
The purpose of CasJobs is to permit large queries, phrased in the Structured Query Language (SQL), to be run in batch queue. A Quick run button on the open "Query" page is provided to test submission syntax.
Knowing SQL helps, but if you don't know SQL, you can Google "SQL tutorials". This implementation of CasJobs is designed for you to "fake it".
Casjobs also provides a personal database (i.e. myDB) facility where you can store output from your queries and save stored procedures and functions. This powerful aspect of Casjobs can also be used as a group sharing facility with your collaborators.
CasJobs was originally developed by the Johns Hopkins University/ Sloan Digital Sky Survey (JHU/SDSS) team. With their permission, MAST used version 3.5.16 to construct three CasJobs-based tools for GALEX, Kepler, and the HSC.
Acknowledgements of the use of CasJobs in publications should note its authorship by the JHU/SDSS team and list the original site as http://casjobs.sdss.org/CasJobs.
Authors are also asked to acknowledge the "Hubble Source Catalog" in the text of the paper, and consider a reference to the Whitmore et al.(2016) paper describing the HSC.
