... PIF

The Pixel Illumination Factor (PIF) is a number between 0 and 1, which expresses the theoretical degree of illumination of each detector pixel for a given source in the sky.

... analyze

It is no more needed to add the extension `[1]' but the name of the FITS file (`swg.fits') is needed unless you use the very basic format without the directory path `scw/0039/' and without the final `/' as shown below [1].

... shells

If the setenv command fails with a message like:`setenv: command not found' or `setenv: not found', then you are probably using the sh family. In that case, please replace the command `setenv my_variable my_value' by the following command sequence: `my_variable=my_value ; export my_variable'. In the same manner, replace the command `source a_given_script.csh' by the following command `. a_given_script.sh' (notice the leading `.' !).

... parameter

To read a given extension in XSPEC (version 12) you have to specify it in curly or squared brackets (depending on the spectral type): If you want to examine in XSPEC the spectra produced at scw level, you can load them as e.g., data scw/*/isgri_spectrum.fits [3] or as data XXX_single_pha2.fits{3}.

...specat.fits

specat.fits has to be of the ISGR-SRCL-RES type, meaning that it has to be created by the imaging step (with OBS1_DoPart2=1, since this file is created at mosaic stage). See section 7.2 to learn how to go from the imaging result file isgri_srcl_res.fits to your specat.fits, to avoid software crash.

Please note that the images that you intend to merge MUST have the same energy boundaries i.e. all the ScW maps must have been analysed in the same way. You cannot merge a 20-40keV map with a 30-50keV one.
