In this section we give a brief overview of the INTEGRAL data analysis methodology. The analysis
is achieved by four independent instrument specific analysis chains (scripts). All of them follow
the same approach. First thing to do is to select the science windows you want to analyze. From
the list of the selected Science Windows you create the Observation Group (Table 8).
If you want to analyze only some time periods within your Observation group you define your own good time
intervals (Section 6.2). After that, you are ready to launch the analysis script; you can find detailed examples
in the cookbooks of the analysis user manuals [1] - [4].
If the script ends with an error, you can check the reason of the failure on our error-code web-page

To analyze the produced images it is convenient to use a program creating region files for DS9 from the produced catalogs (Section 6.3).
