In-flight Calibration Strategy

• Effective area:

  • Hot white dwarfs at > ~50 A: Sirius B, HZ 43
    • model atmosphere predictions
  • Blazar PKS 2155-304, quasar 3C273 < 50 A
    • power-law continua
  • Conservative approach: only reasonably well-understood modifications are allowed

• Dispersion Relation, LRF

  • Narrow-line point source Capella (G0 III+G8 III)

• Supplemented with GO observations
