Proposed TOC for the Report

  • Intro:
    • Compact Objects:
      • White Dwarfs:
        • CVs
          • Types:
            • Magnetic
            • Intermediate
            • Double Degenerates
            • Other relevant types
      • Neutron Stars:
        • qLMXB
      • The Secondaries
        • M type
        • K type
    • Globular Clusters:
      • NGC6397
        • The Motivation for NGC 6397
        • Harris Info
        • Compact Object Population (15 CVs candidates, 3 neutron stars (1 qLMXB))
    • Spectroscopy:
      • Integral field spectrograph
        • MUSE
  • Observation and Methods:
    • MUSE Science Verification and Commissioning Data:
      • Public release data and (Husser et al. 2016) work and available processed data
    • Data Reduction:
      • MUSE Data Reduction Software:
        • CPL
        • EsoRex
        • MUSE “dynamical libraries” or recipes
      • Public GitHub Repo with all code to reduce the data:
        • Include README ? and wiki if I ever finish it
    • Spectra Extraction and analysis ?
      • QFitsView (extraction, sum 5 pixel area)
      • IRAF/PYRAF (fitting, smoothing, hopefully cross correlation)
      • Python (Clustering Exposures, Plotting)
  • Results:
    • Spectra:
      • “Brights”
      • “Faint”
      • ’Intermediate"
      • Neutron Star
    • Variability:
      • Magnitude now, in (Cohn et al. 2010) and (Kaluzny et al. 2006) range
    • Mass estimation:
      • DP/FWHM vs. q according to [casares_mass_2016]
    • Secondary Star:
      • M star spectra from (Husser et al. 2016)
      • Lack or presence
  • Discussion:
    • Two population:
      • Dynamically vs. primordial?
    • Magnetism ?
    • X-Ray ?
  • Future Work
    • Dr. Guillot MUSE proposal for the qLMXB
    • Optimal spectra extraction (Horne 1986)
    • Create a Docker container for the data reduction with necessary software.
    • Create an Amazon Machine Image to be able to run analysis with the Amazon Elastic Compute Cloud. An example of something like this done in academia is the work of (Ragan-Kelley et al. 2013)
