The 'critical scripts' are:

• ozdes_spectra.py (which relies on ozdes_tools.py) mostly for just looking at the spectra.

• Janie's getPhoto.py (https://github.com/jhoormann/OzDES_getPhoto) for fetching magnitudes from photometry, OR querying the databases yourself for the magnitudes (which is what I ended up doing).

  • for DES DR1 queries, I used the DES easyaccess package (https://github.com/mgckind/easyaccess), queryDES.py to query and readQuery.py to read the output.
  • for NOAO queries, I used their online query interface (https://datalab.noao.edu/query.php) and pulled from the image headers.

• Janie's calibSpec.py (https://github.com/jhoormann/OzDES_calibSpec) for calibrating the spectra using the magnitudes from the photometry.

• fit_spectra.py (which relies on generic_peak.py) for fitting Gaussians to emission lines. This is an MCMC fitter and fits up to three peaks at once.

• mass.py (which relies on ozdes_mass_tools.py) for calculating BH masses from fit parameters.

  • H beta and H alpha constants come from this paper: https://arxiv.org/pdf/astro-ph/0508335.pdf
  • Mg II constants come from John's paper: https://arxiv.org/pdf/1410.1539.pdf

Everything else is 'old scripts' or 'temp scripts' that I decided to toss in here as a back up.

• ozdes_legacy.py, ozdes_database.py: old / scrapped scripts from summer 2019 when I started this project.
• FWHM.py, integrate.py, straighten.py: temp scripts when I was figuring out how to calculate mass from fit parameters.
• read_obs.py, all_mass.py: temp scripts I made for file-reading convenience and cranking through calculations.
• spec-xxxx-xxxxx-xxxx.fits: some SDSS spectra I practiced fitting on, from this paper: https://arxiv.org/pdf/1509.03634.pdf
• links.txt: just a backup of some links I had bookmarked as I had to refer back to them a lot.
