Data files and descriptions

Kyuseok Oh

The OSSY database is consist of 6 files in fits format :
(note that objects are sorted in the same order they appear in all fits files)

  1. OSSY_SDSS_parameters.fits  [Download: 36MB] [description]
    : General information describing objects.

  2. OSSY_absorption.fits  [Download: 187MB] [description]
    : Stellar absorption line strengths.

  3. OSSY_emission_flux_errors.fits  [Download: 405MB] [description]
    : Intrinsic emission-line fluxes and errors. The values of Emission line strengths are derived from 'intrinsic' shape of spectra, which is affected by both galactic and internal reddening.

  4. OSSY_emission_aon_ew_sky.fits  [Download: 359MB] [description]
    : Gaussian Amplitude / Noise (AON) of the emission-lines, Equivalent Widths (EWs), and flags for the sky contamination. Skyline contamination (λ5577.0, λ6300.0, λ6363.0Å) is provided with '0' (telluric-free) or '1' (contaminated).
