   * A7: General magnitudes comments:  (GENE?)
      * 1. gMeanPSFMag - gStackPSFMag is bimodal: two peaks one at -0.03 and one  at 0.12 (clearly separated) and not really the case for other bands

+       * a. '''EAM : I do not see this effect in SAS 11 (but have not plotted it for SAS 10).  the figure below shows g(PSF,EXP) - g(PSF,STK) vs g(PSF,EXP) and a histogram of the difference.  I do not 2 peaks, but I am concerned about the 0.05 mag offset'''.

      * 2. ?MeanKronMag & ?MeanKronMagerr: they span a ridiculous range (which  is not the case for ?MeanPSFMag and ?MeanPSFMagerr, hence the reason to flag it)
