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.
