Science use Cases for Time Series

  • Use Case #1: Follow-up characterisation of supernovae (based on Zhang et al. arXiv:1208.6078v1)
    • Show me a list of data that satisfies
      • Datatype= Photometry or TimeSeries/lightcurves
      • Axes include time
      • Axes include magnitude
      • Information on photometric band
    • Notes:
      • Pre-explosion photometry is necessary to obtain the maximum brightness
      • Multiband photometry is required to study wavelenght dependences in the decay phase
  • Use Case #2: Exoplanet studies using radial velocities (based on Lagrange et al. 2012)
    • Show me a list of data that satisfies
      • Datatype= TimeSeries/radial velocity curves
      • Axes include time
      • Axes include radial velocity
  • Use Case #3: Asteroseismic studies of pulsating variables (based on García-Hernández et al. 2009)
    • Show me a list of data that satisfies
      • Datatype=TimeSeries/powerspectra
      • Axes include frequencies
      • Axes include power
  • Use Case #4: Eclipsing binary systems (based on Gómez Maqueo et al 2009)
    • Show me a list of data that satisfies
      • Datatype=TimeSeries/lightcurves
      • Axes include phase (or axes including time and information on the period available in the metadata)
      • Axes include differences in magnitudes
