AGN-Specfit

AGN-Specfit (AGN Spectral Fitting) is a modified version of QSFit. It is created as a pipeline to perform the analysis of SDSS Type 1 Active Galactic Nuclei optical spectra. To make use the pipeline, you have to:

1. Add SDSS spectra files to "data" directory.
2. Create list of file names, redshifts, and E(B-V) in "QSO_name.csv".
3. Create directories which are named:

• "output" and "table", to store the calculation result in nested and flattened structure files respectively.
• "plot", to save all the plot data to be later loaded in GNUPLOT.
• "result", to store the merged tables from "table" folder.

4. Start an IDL session in your working directory. Then, compile and run the IDL scripts:

IDL> CD, "D:\path\where\AGN-Specfit\is\located"
IDL> compile
IDL> process_spectra

5. Use the python scripts to combine all tables in "table" folder into one concatenated table. You have to install necessary modules first:

pip install -r requirements.txt
python multi_make_table.py

6. You can specify which columns to keep by modifying "result/columns_to_keep.txt" files.
7. Edit the scripts if necessary to suit your needs.
