 I have finished another iteration on source size analysis.  I feel
 fairly confident of the extended source and CR identifications.  They
 are not perfect, but they are in pretty good shape.  The CR IDs use
 the moments to find things smaller in one dimension than a PSF, while
 the EXT is set for things larger than a PSF in one dimention. 

 There still seems to be some trouble with SATSTARS : these are being
 set for sources which are fainter than the SAT limit -- I'm not sure
 if this is due to the quality of the PSF fit or if they really are
 SAT, but have integrated fluxes lower than expected (underfitted in
 PSF).

 Additional Parameters needed from psphot for distinguishing dipoles:

 -- note regarding CfA parameters -- 

  Here are our settings.
  
  Note that Fpos is the flux which is 3-sigma above background, and
  Fneg is the flux which is 3-sigma below background.
  
  Npos is the # of pixels with flux which is 3-sigma above background.
  
  etc.
  
  # for positive objects:
  # Ngood = Npos, Nbad = Nneg, Fgood = Fpos, Fbad = Fneg

  # for negative objects:
  # Ngood = Nneg, Nbad = Npos, Fgood = Fneg, Fbad = Fpos
  # FRATIO=Fgood/(Fgood+Fbad)
  # NRATIO_BAD=Ngood/(Ngood+Nbad)
  # NRATIO_MASK=Ngood/(Ngood+Nmask)
  # NRATIO_ALL=Ngood/(Ngood+Nbad+Nmask)
  DC_FRATIO_MIN         0.75   
  DC_NRATIO_BAD_MIN     0.70   
  DC_NRATIO_MASK_MIN    0.60
  DC_NRATIO_ALL_MIN     0.50
  DC_NGOOD_MIN          3

  We have several stand-alone psphot versions, and a few different
  psphotReadout versions called by other programs.  Here is a complete
