WHY ARE WE OBSESSED WITH BKG ? WHY ARE WE OBSESSED WITH BKG ?
De Luca & Molendi 04
Detailed knowledge of bkg is crucial to measure faint diffuse X-ray sources: outer regions of clusters and groups and the CXB

EFFECT OF THE ORBITEFFECT OF THE ORBIT
Moretti et al in prep.
Higher bkg for high orbit satellites and significant variation due to solar acitivity. In LEO even very different design (Suzaku and Swift) have similar bkg

CONCLUSIONSCONCLUSIONS
CAREFUL CHARACTERIZATION OF THE BKG FOR MANY SATELLITES CAN HELP IN IDENTIFYING PROBLEMS AND PROPOSE SOLUTIONS
BKG WILL BE CRITICAL FOR MANY OF THE SCIENCE GOALS OF ATHENA
