Hyper Suprime-Cam: data analysis and management system

Abstract

We report our activity on development of data analysis system dedicated for the Hyper Suprime-Cam (HSC), which is a future wide-field camera at Subaru Telescope. The data analysis system (HSC-ANA) is intended for the following achievements: (1) automated processing of an unprecedentedly huge amount of data frames without frequent human interactions to achieve required depth and area of the key survey projects (2) immediate release of best-effort object catalogs together with calibration information to user communities to maximize scientific outputs. The system also enables general users to efficiently use archive data by providing appropriate meta data describing data quality. We start with constructing a prototype data analysis system which involves minimal functions to process data for the current prime-focus camera (Suprime-Cam). The prototype system is developed based on combination of newly developed and existing software packages for imaging data and the framework middleware which communicates with databases. This system is planned to help observers to perform their observations with Suprime-Cam. Once the prototype system is evaluated, it will be scaled up to the full HSCANA system.
