1) Download the compton program .

2) Copy compton.tar.gz to <PATH>, where <PATH> is an arbitrary location and then:

• go to <PATH>: cd <PATH>
• unpack archive: tar -xvvf compton.tar.gz

3) Compilation:

• If previous compton binaries exist, do: make clean.
• Run install.sh: ./install.sh

4) Generate arbitrary input SEED spectra using XSPEC:

• Run XSPEC.
• In XSPEC shell, choose the model: XSPEC>mo <xspec model>.
• Define the energy array: XSPEC>dummy <E_min> <E_max> <N_bins>.
• Choose output device for plotting: XSPEC>cpd /xw.
• Plot spectrum (EF(E)): XSPEC>plot eemo.
• Go to interactive plotting shell: XSPEC>ipl.
• Save spectrum: XSPEC>wdat <seed_file.dat>.

5) Run compton, using the run_compton.sh script: ./run_compton.sh <tau> <kTe> <distribution> <seed_file.dat>, where:

• <tau> - Thomson optical depth;
• <kTe> - electron temperature in keV;
• <distribution> - distribution type: HOMOGENEOUS, CENTRAL, S_T, CONST_IRRADIATION, THIN_SOURCE or THICK_SOURCE.
• <seed_file.dat> - SEED input file generated in step 4).

6) The output file comp_tau<tau>_kTe<kTe>_<distribution>_<seed_file.dat> should appear.

• First column in output file is Energy in keV;
• Second column contains resulting spectrum (EF(E)).

7) More control parameters can be set in run_compton.sh file.

• For detailed description, see instruction .
