Use Cases

The requests stem from visualization use cases:

  • 1-D spectra from Spitzer’s Infrared Spectrograph have multiple spectral orders
    • Spectral orders can overlap in wavelength
    • Plotting a Spitzer spectrum without accounting for orders gives you a mess
  • SEDs often include limits on measurements
    • these can be upper or lower limits
    • Plotters need to indicate limits clearly to avoid scientific misunderstanding
    • SDM1.1 has an ad-hoc representation for upper limits (only) which may be usable, but is conceptually incorrect.
