These are the new photometry plots.  These plots are similar
to the plots I sent a couple of weeks ago with the following
improvements.  The earlier plots were attempts to verify that
the latest modifications to the photometry scripts (which
I generally call tweaking fluxes) were accurate.  These new
plots are from newly modified photometry scripts which use the
same tweaking routine except it uses it twice; first to correct
under-subtracted sources, and a second time to correct the over-
subtracted sources.  This gives us another level of improvement
in our photometry accuracy (if you still have the old plots, 
consider this step an improvement on all the points that were
below the 0-line which were the under-subtracted sources).
I now have the band 4 photometry good to a Signal/Err = 5.0
I believe.  These new plot are slightly different from my previous
plots by the fact that I now plot 3 different panels,
 top panel - all sources above the 5 Signal/Err level,
 middle panel are the low background sources,
 and the bottom panel are the high background sources.
