The output file of model/spectrum depends on its
output mode and on its parameter mode,
which can be set in the parameter file.
If for spectral fitting the output mode parameter
is chosen only parameters of the model are stored
in the table, whereas the option spectrum allows
to output the whole spectrum to the table.
If a 
grid is performed the result is an image
of 
.
All spectral output files are written in real format.
