Remarks on the EEMC calibration in 2006

 
Abstract: We examine pi0 invariant mass spectra from the 2006 run, using isolated pions with no energy deposited in the 1st preshower layer w/in a radius of 0.3.   An invariant mass of 139.0 +/- 0.3 MeV is reconstruced, with no observed dependence on pseudorapidity.  Conversion rates observed by the preshower layers for identified pi0 decays, indicate that, on average, there are three photons w/in the cluster used to measure the energy of the pion.
