Hi Pascal,

You're way ahead of me. I'm just back from the ILRS workshop and have 
a lot of work to do yet.

Your conclusions match mine, though you've clearly done a more 
detailed job of looking at the correlations with the geometry of the 
pass. I agree that the effect is not always a quadratic. My greatest 
concern is the increase in the 'saturation'. At some point, will the 
oscillator be so sensitized to radiation that other parts of the 
orbit start become affected? We'll have to see.

See you in New Orleans,
JR
