Toolkit of automated database creation and cross-match

摘要

Astronomy steps into a fullwave and data-avalanche era. Astronomical data is measured by Terabyte, evenPetabyte. How to save, manage, analyze so massive data is an important issue in astronomy. In order to letastronomers free of the data processing burden and expert in science, various valuable and convenient tools(e.g. Aladin, VOSpec, VOPlot) are developed by VO projects. To suit this requirement, we develop a toolkit torealize automated database creation, automated database index creation and cross-match. The toolkit providesa good interface for users to apply. The cross-match task may be implemented between local databases, remotedatabases or local database and remote database. The large-scale cross-match is also easily achieved. Moreover,the speed for large-scale cross-match is rather satisfactory.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
