Calibration strategy:

Internal calibrators:

• bridge gap between laboratory and in-flight calibration:
  internal calibrators used to re-establish calibration in-orbit

• tied to astronomical standards via calibration observations:
  Planetary nebulae, stars, ...

• build together with cal-files the reference for science observations

Calibration tasks:

• in general:
  • fill the calibration files
  • check calibration regularly
  • monitor variability

• especially:
  • wavelength calibration
  • photometric calibration
