Hi, Peter,

The data has not been multiplied by anything; this is a raw count
difference spectrum for one pair of gondolas (1 and 9).  Yes, you can
really still see muSR at almost 5 lifetimes! 

The asymmetry comes from a difference in the acceptance of the top and 
bottom counters, which leaves a small non-oscillating exponential decay.

Thanks,
