To clarify some of the columns:
- Type: Broad astrophysical object category T-Tauri Star, X-ray binary etc
- Best Purpose: what can be calibrated with it (e.g. fluxes, line response shape, relative sensitivities, absolute uncertainties, very good in Fe lines, etc)
- Waveband: Best waveband for calibration
- Issues: Any problems or items of note in the spectrum (e.g. is a binary so line centroids vary; has no Fe lines; spectrum varies)
- X-ray flux: hopefully self explanatory. Just a rough estimate is fine.
- Restrictions: Any issues with potentially scheduling the observation - variable source etc.
- Missions Used By: if the object has (or is scheduled to be) used by other missions as a semi-regularly observed cal source, list them here.
- Other notes: anything else
