GOLIA: an INTEGRAL archive at INAF-IASF Milano

TL;DR

This paper describes the development and contents of a comprehensive INTEGRAL data archive at INAF-IASF Milano, providing processed data and analysis tools for studying hard X-ray sources from 2002 to 2011.

Contribution

It introduces a publicly accessible archive of processed INTEGRAL data with dedicated analysis scripts, facilitating long-term X-ray source studies.

Findings

Archive includes data from December 2002 to August 2011.

Provides images, source lists, and light-curves in multiple energy bands.

Analysis tools are publicly available for community use.

Abstract

We present the archive of the INTEGRAL data developed and maintained at INAF-IASF Milano. The archive comprises all the public data currently available (revolutions 0026-1079, i.e., December 2002 - August 2011). INTEGRAL data are downloaded from the ISDC Data Centre for Astrophysics, Geneva, on a regular basis as they become public and a customized analysis using the OSA 9.0 software package is routinely performed on the IBIS/ISGRI data. The scientific products include individual pointing images and the associated detected source lists in the 17-30, 30-50, 17-50 and 50-100 keV energy bands, as well as light-curves binned over 100 s in the 17-30 keV band for sources of interest. Dedicated scripts to handle such vast datasets and results have been developed. We make the analysis tools to build such an archive publicly available. The whole database (raw data and products) enables an easy access to the hard X-ray long-term behavior of a large sample of sources.
