A Walk Through the JEM-X Analysis

After setting up the data and the environment, you are ready to call the analysis script on the Crab region observations defined above and stored in the jmx.lst file.

Firstly, create an Observation Group (see the description of the executable og_create in the ``Toolbox'' and ``Data Analysis'' sections of the Introduction to the INTEGRAL Data Analysis [1]):

og_create idxSwg=jmx.lst ogid=crab baseDir="./" instrument=JMX2

As a result, the directory $REP_BASE_PROD/obs/crab will be created. It contains the files og_jmx2.fits and swg_idx_jmx2.fits as well as the subdirectory scw necessary for the analysis (see Fig. ). The file indicated in idxSwg is automatically interpreted as a fits file when the name includes a ``+'' or ``['' sign.
