Understanding the outputs
Output files are written to the sims/ directory (unless specified otherwise) after the code has fully converged. The code generates multiple output files with different suffixes:
.pdr.fin: Species abundances
.line.fin: Line emission data
.cool.fin: Cooling functions
.heat.fin: Heating functions
.COOL.spop.fin: Level populations for each coolant (where
COOLis the coolant name)
Note
Outputs are in ASCII format and can be plotted using standard tools like GNUPLOT or PYTHON.
