  6. Cross section of the support panel.
  7. ISGRI and PICsIT division in modules and submodules
  8. Schematic view of the PICsIT layer.
  9. IBIS sensitivities for the various detection techniques.
  10. Science Analysis Overview
  11. Structure of the directory created with og_create
  12. Main page of the IBIS GUI
  13. Imaging page of the IBIS GUI
  14. Overview of the IMA level products
  15. A part of the GROUPING extension table of an isgri_sky_ima.fits file.
  16. INTENSITY (left) and SIGNIFICANCE (right) mosaic images in the 20-40 keV energy band.
  17. ScW-per-ScW lightcurve of 4U 1700-377 in the 20-40 keV energy band
  18. Page of IBIS GUI for Spectral and Ligtcurve extraction
  19. Energy binnings can be defined through either one of the above parameter sets, for spectra as well as for imaging (here we put only the common part of the parameter name. For example you should use IBIS_II_ChanNum or IBIS_nregions_ima for imaging; and IBIS_SI_ChanNum or IBIS_nregions_spe for spectral analysis).
  20. List of sources used for the spectral analysis
  21. Total spectrum of 4U 1700 377 fitted with a cut-off powerlaw model.
  22. Lightcurve of 4U 1700-377 in the 20-40 keV energy range with 100 sec binning.
  23. Crab power spectrum.
  24. Main page of the IBIS GUI
  25. PICsIT page of the IBIS GUI
  26. Crab significance image in the keV energy band as seen by PICsIT.
  27. PICsIT Crab spectrum extracted from the mosaic.
  28. Composition of the main script ibis_science_analysis. For further descriptions of the BIN BKG steps for the DEAD, IMA and BIN_S levels, see Figures [*], [*] and [*] respectively.
  29. Overview of the binning - background step for Imaging.
  30. Overview of the binning - background step for Spectra.
  31. Overview of the binning - background step for Lightcurves.
  32. ISGRI low threshold position as function of INTEGRAL revolution number. Notice that this is the lowest limit of detectable photons, but individual pixels might have a higher low threshold. The recommended energy ranges to analyze spectra are given in Section [*], ISGRI known issues.
  33. SPSF for the IBIS/ISGRI telescope.
