Data access and analysis system for Gaia data handling during operations at Italian DPC: scientific validation and results monitoring approach in support of the AVU operations

摘要

This document is the first, systematic description of the approach adopted to support the operations of theGaia Astrometric Verification Unit (AVU) systems. A further subsystem that collects and provides useful toolsfor a scientific oriented approach to Data Analysis and Access is designed and integrated in Data ProcessingCenter of Turin. Specifically, its aim is to provide to the AVU system an operative and versatile set of diagnosticelements useful for the analysis and the manipulation of the stored data. Examples of the different scenariostargeted by the operation efforts are: - Visualization of the “Runtime” mission status; - Archive and recoverydata, using graphs and log files contained in the Data Base; - get “On-demand” information for ad hoc analysesand data mining; - Production of tables and reports retrieving custom data in the database. The different casesare described in terms of the methods and of the environments in which these take place.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
