Radiation field 
In the example #9 (XFELdriven
plasma case), the mean intensity at 3.096E+03 eV is the same as that
at 3.103E+03 eV.
Does this mean that the intensity is
energyindependent within this energy range and it is zero otherwise?

The
radiative rates are calculated by using the mean intensities given at
the energy grid.
In this particular example, the
radiation field is defined uniform between the two grid point and
zero outside the energy range
There is a way to
extrapolate the radiation field outside the defined range.
One may put the additional number at the first line then the code
will extrapolate the radiation field with 1/(hv)^3 * exp(hv/Tr) to
higher energy and linear extrapolation to lower energy.

Radiation field 
The example #9 shows that the mean intensity
increases from 9.301E2 to 9.301E15 during the time interval of
1.0E12 seconds.
(i) How does the code estimate
the intensity at an intermediate time?
(ii)
Is the intensity zero after 1.0E12 seconds? 
(i) Between the time steps, the
mean intensity is linearly interpolated.
(ii) If the
time of calculation exceeds the given input time,
the
code will complain and stop.
