which expresses the theoretical degree of illumination of each
detector pixel for a given source in the sky.

- 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 `.' !).

- ... interest.
- The number of sources
in the input catalog should be limited at a relatively small
number (a few tens at most) to increase the stability of
fitting routines and reduce the computing time.
Sometimes, the combination of narrow energy bins and a large number of sources
can lead to erroneous results in some bins of a spectrum in one or more some science windows or
even to a software crash. This is true especially in the
late part of the mission, with an enhanced number of dead pixels in the detector.
Whenever in an average spectrum,
a spectral bin shows a large variation from neighboring pixels,
the user is invited to check carefully if in one or more science windows,
the fit has not converged to an extreme value with artificially small uncertainty.

- ...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 to learn how
to go from the imaging result file
isgri_srcl_res.fits to your specat.fits, to
avoid software crash.

while the file isgri_user_bins_ima.fits is stored only if energy binning is defined using IBIS_nregions_ima and related parameter.

- 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.
