INTEGRAL Science Data Centre

Download INTEGRAL Software

The Off-line Scientific Analysis (OSA) software package contains all tools to perform INTEGRAL data analysis of any of the four instrument aboard. To install it, download here the relevant packages and follow the instructions of the Installation Guide. Once the installation is completed and tested with the provided Test Data, go to the documentation tab, and consult first the "Getting started" document.

Third party software is useful to allow you to follow the analysis examples provided in our documentation cookbooks.

The INTEGRAL Burst Alert System (IBAS) client software is only useful to receive the real time gamma-ray burst (GRB) alerts (e.g. for quick follow-up observations by ground-based telescopes).
