+-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.
