Contained herein are the background asymetries for the longitudinal single and double spin asymetry for 2006 inclusive pi0s in the EEMC.  The results are computed the same way as the signal, but the raw number of counts are multiplied by one minus the signal fraction instead of the signal fraction.  The background asymetries were computed in the mass peak range (100-200 MeV) and in a right side band region (300-500 MeV).

A_L Blue

Order: signal in peak, background in peak, background on right side.

A_L Yellow

Order: signal in peak, background in peak, background on right side.

A_LL

Order: signal in peak, background in peak, background on right side, Weihong's background estimate.

Conclusions

Background asymetries are consistant with zero, within at most 2 sigma or less.
